iPhone 12 Pro Yellow Screen/Tint? Display seem "Warm"? Check here first!

Holy crap. I thought this guy was crazy, but he's right! With both my iPhone X and 12 Pro Max displays off, the reflection of my white ceiling is noticeably more green on the 12 Pro Max, so it's definitely a hardware issue, possibly glass that is slightly green tinted. I wonder if the new ceramic shield glass is what's defective and not the displays themselves.
I'm not seeing that on mine, although it is interesting that the Note 20 Ultra and Fold 2 both have Gorilla Victus (ceramic shield essentially) and also show warmer color temps.
What I find most interesting in this graph is not the green being slightly higher than normal, it is the red and blue significantly lower than they should be at lower brightness. The lack of red and blue highlights the green.
It seems to me as one of the phone are tuned by color filter and higher contrast on. Sorry when I am wrong but the blue, grey or green background of the buttons looks not like the standard should looks.

Surely this has to be a software problem, how can BOE (not sure if they actually make iPhone 12 screens), LG and Samsung all have similar problems over the entire iPhone range. If it was just one manufacturer I could understand but all of them having the same problem doesn't seem right.
What's also interesting, is that this graph lines up with the other RBG balance graphs I saw of display units of Samsung Galaxies and generally other OLED phones released this year. I think this might be an industry wide issue this year.
I...also took the time to look at the other side of the river so to speak, and researched if other phones this year exhibited the same issues and look and behold:

Looks like Samsung phones, the Google Pixel 4, OnePlus 8 Pro and Nord are also experience the green tint issue with their OLED displays.
Saving grace is, that apparently Samsung sorted this stuff out with a software fix, so there is hope left for us as well!
Faulty "Ambient light sensor"(ALS)....how many of you have this issue?
Looks like my iPhone X actually has a bit too much red, but I guess my eyes are more sensitive to too much green.

Wow that's actually interesting. Thought there would be a much more pronounced blue throughout the graph but the 12 actually fairs better aside from the low end.
Decided on returning my 12PM for the time being. Asides from the screen difference this year, also found mine had part of the coating between the frame and glass peeled off. It was minor, but it was there and once I saw it there was no going back. Blame it on my OCD.
Also returned a 12 Pro for the same reason.
Apple’s quality this year has been terrible. I’ve never had problems as this with any phone purchases in the past. Disappointing for mobiles costing over a grand.

At lower brightness the green is not that much different. Red and blue look better at lower brightness. Overall more consistent.
The iPhone X color temperature is actually 6554K, which is surprising, because it looks cooler than my 12 Pro Max, which is 6521K. I was expecting the X to be in the neighborhood of 6700-6800K. I wonder if the off axis color shift is altering my perception of how cool the screens are. I don't know how to measure at an angle, but my X definitely gets very blue when I look at it from an angle, and my 12 Pro Max gets very green when I look at it from an angle.

I think someone mentioned it on the thread way back, but I believe you can have an accurate white balance and still have colors be off. I could be wrong though. I'm doing some googling right now to find a definite answer.
Just want to clear one thing up. The x axis on these graphs is not brightness. All of the measurements are taken at the same brightness. The x axis is grayscale, so 0% is black, 25% is dark gray, 50% is medium gray, 75% is light gray, 100% is white. So the 12 Pro Max graph, for example, is telling us that, at this specific brightness (42%), white is well balanced, but dark grays have a lot of green tint.
Mine is silver and is slightly warmer than the 11 PM I had which wasn’t yellow. My wife’s gold looks just like mine.
BOE is not in any iPhone 12s yet. There was just an article last week about them not passing Apple's certification to become an iPhone display supplier. So it's just LG and Samsung, and I suspect Samsung might still be making the vast majority of displays since they've been at it longer and probably have better yields.
so are the duds LG?
I know there's bad Samsungs too, especially since X/XS/11 Pro were all Samsung and plenty of those
but the new green tint issue / not perfect blacks? dont recall that being a problem in the past

No, mine is a Samsung and it has green tint. There are duds from both, but we don't know what the cause is. Might not even be the displays themselves... could be flaws in Apple's calibration process or flaws in the ceramic shield glass. It's all speculation at this point.
is that 3u tools identiifer accurate?
would love to see a good LG vs a good Samsung compared of the same model
