I'm inclined to agree with this. I compared my new 11 Pro out of the box to floor models in 2 local Apple stores, and the demo models were definitely slightly cooler, but dimmer at max brightness (with TT and AB off). Obviously, their screens would be more "broken in" than mine. I've also been measuring color temp at pure white for the past 3 days, and the screen itself has gotten about 200 Kelvin cooler since I unboxed it 4 days ago. Was 6553K, now 6760K. Don't know how long that trend will last, but there's definitely some kind of reaction/aging/drying gong on.

That said, I calibrated my macbook pro monitor to nec 709 (which would contain a D65 whitepoint). It also now measures about 6600 K, but looks noticeably cooler with purer whites than my 11 Pro. I think Apple may be playing with RGB values in software somehow - handicapping blue, or augmenting red - but still keeping it on the 6500K curve.

In any case, it's completely inexcusable that we can't embed icc profiles, or at a minimum, independently adjust RGB channels and white balance, like we can on any TV set made in the last forty years.
What brightness are you measuring the display at and are you measuring in the same spot every time? OLED screens’ color temp can change depending on the brightness (Depends on how consistently they balance Red, green and blue in the grayscale through the brightness scale). I calibrate my display to 200 nits before measuring and I will also do it at whatever 100% brightness is. Also, the RGB output in one spot could be different a few mm over so I’m curious if your screen is actually cooling down? Unless you are measuring multiple spots for an average?

From what I can see with my 3 displays there just isn’t enough blue but still one has a color temp near 6500K and the other is 6300K. It’s like they are trying to target 6500K without consulting the black body line of true white, where Illuminant D65 is (0.313, 0.329) on CIE 1931. You can have a CCT value along the iso-CCT lines that equal 6500K while actually going towards quite greenish or magenta looking instead of white. Just saying simply targeting 6,500K does not equal D65 white. Anyhow, it’s within tolerance, though I think it should be better (100 IRE [pure white] is showing .005 xy from the black body line) and we’ve been coming from Apple displays with much cooler white points so we really notice it. I just don’t know why Apple is suddenly swinging for warmer color temps, unless that is their way of reducing blue light? But that doesn’t make sense because these white points are looking a lot like the S10 and my Note 10 plus that are of a warmer color temp too and Samsung displays have looked like this on their rec 709/sRGB mode for a long time. I’d like to pick their brains.

Holy crap, guys:

I think that might have to do with the "wallpaper bug." It seemed that picking a new wallpaper could trigger the screen to look dull in vibrancy. This happened with an iPhone I returned last weekend. I got the new one and the screen looked so much more vibrant in colors than the one I was returning (still warm toned though). But then when I factory reset that iPhone I was returning, the phone looked identical in vibrancy to the new one I was keeping (also still warm toned). Hope that makes sense lol.

Dead center at full brightness. Swatch is 255,255,255.

From what I can see with my 3 displays there just isn’t enough blue but still one has a color temp near 6500K and the other is 6300K. It’s like they are trying to target 6500K without consulting the black body line of true white, where Illuminant D65 is (0.313, 0.329) on CIE 1931.

Exactly. I think they’re intentionally handicapping the blue channel (relatively speaking). I wouldn’t read too far into it but the default wallpaper on their demos and promo material is also that very red/orange abstract design, which would accentuate a warmer screen. Maybe it was intentionally chosen?

I'm just guessing here, but since the OLED blue emitting diodes do need/drive more energy within their lifetime (they wear out way faster), and especially red has a far higher life expectancy in that regard (green, too), it could be Apple's way of actually making sure that they have the maximum amount of usable and durable panels that are binned and then calibrated to target a warm white point that is also correct for most content. They are using Samsung panels after all, so if they need to pay for each panel, throwing away more panels would mean way higher costs associated, which would hit their margins.

I am pretty sure that Apple is perfectly aware of the variations and from experience with Samsung panels they used in iPads in the past, the panel lottery is something that should not be there in the first place, but Apple seems to be okay with it, since they need a very high output of (especially for Pro phones) panels to be of good quality to be green light for the Pro iPhones.

Let's hope with more and more units out the door, they can keep it to a tolerable level. After all, compared to the vast majority, people complaining here seem to expect perfection, which at that price point Apple sells the Pros, they also have a valid point to make.

I get the feeling it isn’t intentional and that they are having Samsung‘s engineers on it to help them with the calibration. Someone over there must think that D65 is the same thing as targeting “a” 6,500K color temp without paying attention to the coordinates for D65 white along the black body locus line. Just seems silly. They went from understanding the D65 white point with the X to looking just like Samsung’s rec 709 / sRGB white point that has always been stupidly warm, even before they started claiming they’re reducing harmful blue light. I’m just scratching my head on this one.
Holy crap, guys:
Yep, as someone else pointed out, this applies to that silly wallpaper bug. All it took tp fix it was restarting my phone, thankfully. But at least now, I won’t have to do that.

I’m an incredibly OCD person and I notice the littlest things. Is this slight yellowing something that will go away with time? Because it looks like I’ll have to keep it as I saved up the £1049 to but it but in the apple store there was a problem with my card, so my mom bought it then I gave her the money etc... but then when I mentioned this to her that my screen was yellower and swapping it could solve it she called me stupid ‘as any non tech savy person would. This is heart wrenching because I saved up for so long then when something isn’t right with it I’m not being allowed to switch the phone. Is this something that could be fixed in an update in the future, with a possible white point slider or even just revering the screen to normal? I’m just so disappointed in myself and apple. Wish I just sorted my own bank account out so I couldn’t made the transaction and not relying on someone else who will not believe anything I am saying.

Nice story. I don't believe it, neighter apple employees who are posting here. Move on.

Has it fixed the issue?


Move on? Seriously? If I’m buying a phone for 1000 dollars I want to know that’s it’s right and not defective. Even if you wouldn’t class this as defective I want a normal display for what I’m paying.
Is it pounds or dollars? Make up your mind.
You don't have just a normal display, you have an Apple's standards made display.

My advice to anyone who is not happy with their display, or new phone for any other reason, is to return it under the 14 day policy. Get a refund or gift card, wait a few weeks, and purchase another iPhone if you still want it. Once you are outside of the return window, your options are limited and the "geniuses" are going to tell you your phone is fine more often than not. In my experience the phone/display IS fine in most cases (user error on settings, etc.) Heck I've seen people return displays that are perfect because the old display on their old phone was off but that's what they are used to. However, I have seen bad Apple OLED displays and you spent a lot of money so make sure you are happy. The OLED displays may tend to be a bit warmer than LCD displays. However, they should at least be consistent. Apple is marketing this as a "Pro" device, so it is OK to be demanding about the display.

I would strongly reiterate to wait a few weeks or even months. Let the initial demand die down and the early manufactured models get cycled out. Don't drive yourself, or the poor Apple employees, nuts by exchanging multiple phones at once.

My screen calibration looks unchanged after the 13.1.2 update. As others have said, I think this addresses the wallpaper bug rather than the warmer white point.

I can learn to live with it if it was intentional. I just want to make sure there are not new iPhone 11 pro max phones that have the same white point as last years iPhone XS Max, which I thought was perfect.

What do I know though...I am just a consumer! Haha

Week 33 for me (11 Pro), bought the 09/27 in an AppleStore in France.

very yellow...

if I swap the phone, does the 14 day period reset ?

Alex, I think it resets each time they swap it, I ordered mine online, and the replacement looks like a new order.
if you bought it in a physical store ask them to be sure it’s the same, if not if they have the one you want in stock, just ask for a refund then buy a new one immediately.

I’m in France too, my 11 Pro Max was made on week 35 in FK1, the screen was beautiful when displaying bright images, but with the dark mode it was a disaster, on grey shades the screen was clearly half greenish half reddish, becoming more visible as soon as the brightness was under 50% and at 0% the greys were not greys anymore.

I did a quick check with an i1 display sensor, the top had 40% less red than the bottom, I can’t understand how this can go through quality control and screen calibration process whereas releasing an iOS dark mode full of greys reveals all the defects.

May I ask what software/workflow you're using to test red/green/blue channels? I too have i1 Display Pro, but can't figure out how to individually measure each color - seems the best I can get is just a finished icc profile and color temp. Thanks.

Not to hijack the thread but anybody else have any other QC issues?

I’ve had the screen issues every year; got lucky this time. The only defect is a minor edge blemish on the PVD coating - like the size of a pin head ... can only see it if it catches the light.

So many many things can be worse if you do the iPhone swap lottery ?
I entered the lottery today: Multiple Dust specs in all three cameras (showed up in the pictures) and part of the coating on the front sreen is either coming off or was never there from the beginning. Called Apple Care and they will swap it via UPS. Unacceptable for such an expensive product. Hope my next one is a winner. Keep your fingers crossed.

I want to know the same thing... If it's "normal" it's okay for me but if it's just a defect I want to get a "good one"...

post what week your units are and if they are defective or not.

11 Pro, Space Grey 512 - WARM balance (but no other defects/artifacts):
DNP - China, Chengdu (Foxconn)
Week 38 (16.09 - 22.09)

I was browsing through my camera roll side by side with my old iPhone 7, and I have to say that the color balance of the photos looks much more true to life on the 11 Pro (with yellow/warm white balance). Viewing identical photos on each (taken with the ip7) skin tones, landscapes, blue skies, etc just seem more accurate. I suspect that Apple may have sought to optimize the white balance for this purpose, rather than keep the whites of menus and blank webpages stark and dazzling. It would be consistent with their focused push to improve the camera, and photo processing.

I have the iPhone 11 pro max and my screen is ice white. The whitest iPhone I’ve ever had. I’ve seen others that are a lot warmer. It’s the same every year. Literally every year. It’s just luck of the draw. Funny how all the ones in the Apple store are ice white too. Apple purposely picks the best for the stores and then the actual consumers are in a lottery. Last year I went through 4 to get a good one.
