iPhone 15 Pro Max Screen uniformity and cast

Is there uniformity issues with your panel when viewing it from the normal usage angles? They all tend to tint at some angle. I'd myself appreciate more uniform panel and rather live with some even tint across the screen. These tend to be calibrated pretty warm so that it good to keep in mind when judging the panel.
Not sure what you mean but looking at the picture about your panel serial you posted earlier, yours is LG panel. The string would start with G9xxxx if it was Samsung.
Where can I get the white background image to take a look. My issue is that it’s too yellow (true tone night shift off) also looks a little pink when looking at an angle.
Preferably use something from Safari so that you can have all TT and NS used in their normal strength without additional image enhancements what it does when using photos app.
Simply start with page like google.com and turn your phone sideways and zoom the white filling the whole screen. There is your 100% white test pattern. Also google for Walvision test patterns, you can find several different, just zoom them to fill the whole screen.
As for the uniformity check, I also use some real web sites, simply like going to apple.com and check different gray "boxes" with product images on the front page. I find Apple Watch Ultra 2 box very nice test when moving it up and down and see how gray changes, just look at the gray inside the watch strap loop on either side, very simple but effective way to "reset" your eyes to see actual difference if there is any. It allows you to see better if like left and right side have different tint because I find myself that whole screen one color test patterns tend to cause "snow blindess" type effect, it is much harder to see with bare eyes difference in those (unless it is very bad screen) while if you take a photo of your screen with such test pattern it will immediately reveal how bad uniformity is (which is why you often hear people saying their panel shows issues when take take a photo of the screen but it looks fine viewing bare eyes. Surely camera makes issues more visible better but still).

You should see up to 1 because 0 is supposed to be completely black and if 0 can be differ from black, then your panel it not right either. Anyway what you describe (seeing up to 2) is simple black crush and it is pretty usual issue especially OLED is not that good at lower gray levels even its black level is prefect. If I recall even some MacBooks LCD's tend to do that.
You’re right. It’s been a while since I had to test this. My last iPhone was an XS Max and I upgraded to 15PM now.
Do you refer to the apple ultra watch box in home page?
I tried to get some picture using the google page and zooming the white, there some slight differences.
Hard to post a pic, with the prtective glass it looks like rainbow in soem area. 1pics and 3rd with NS at full strength and TT, zooming google white background, the 2nd without NS.
It’s ok anyway, without the 100% NS it looks great to my eyes

My experience with the LG or GVC panel that they tend to be more yellow. I got an G9N, absolutely love it.
First one was a perfect G9N too, but unfortunaly it had a death pixel in the camera app. 2nd GVC, too yellow for me. 3rd another reseller a charm. Lucky and perfecto for me. No more headace and it's an keeper for years to come!

My main issue is when it’s too warm. I don’t like it. I can live with some tint at extreme angles since I don’t ever look at the screen at those extreme angles.

I mean 6th product from the top on the apple.com front page. Basically all product images with different level gray background on that page is good starting point to evaluate displays. Product photo in the middle allow you to "reset" you eyes to see difference in gray between left and right side.
Not bad, looks like average G9N. Not too much tint difference between left and right, just top part it pinkish.
My G9P is similar but also some pink tint on the right side but from what I tested demo G9P's they all had the same issue. We had bad luck with our G9N (we have got 2 x 15 PM's here) since it has pink tint on the left too besides typical pink tint upper half of the screen but in some situations it still might have edge over mine, not quite sure even after my long tests. Anyway my G9P was better in landscape mode where left and right side did not look too different unlike our G9N where difference was very noticeable in that case. I did not bother jumping to exchange roulette but if I had, I would have aimed for decent G9N myself too, not sure G9P reach the same level

I see. I would myself happily take too warm but even panel instead of cooler but non uniform. My G9P has cooler white than our G9N which is nice and warm. It is hard to describe but my G9P has somewhat bluish undertone with red "tinge", probably panel is cool by nature but adjusted warmer by pushing red to meet desired white balance.
Yes, it is very pleasing warm. Probably that panel is naturally closer to desired white balance.
I wondering if that is the best type after all. Seems very common in this model.
Yes my G9N is very good.
The only issue is, the brightness on the right side from middle to top is a little bit lower than on the right side. But there is no color tint or something only minimal brightness difference.
With the G9P it was the same but there I had a tint from top to bottom when night shift was 50-100%. With this G9N there is no tint even with 100% NS.
Really happy with it 😄

I have found that often this brightness difference can cause tint issues in real use. Have you checked pages like Apple.com comparing left and right side with product images which have light gray background when using NS at 100% + TT?
Anyway, sounds more like you might have found good panel.
Yes I have tested apple.com
The only issues is the brightness issue you can see. For example the picture with the watch I can see it a little bit. The right side is a little minimal bit darker than the left side. But I have to concentrat to see it. In real life you cannot see it 😃
It is also the first panel with no top to bottom tint like the other 4x G9P & G9N I have tested. They all had this even harder with NS at 100%. With this panel there is no difference with NS at 100%.

Wouldn't it be cooler, if it's closer to desired white balance ~6500K? if the color temp is higher(warmer) it's farther from the desired white balance. Am I missing something?
Man, you don't want an BOE display if you have a regular 15 https://www.macrumors.com/2023/12/05/iphone-15-oled-supplier-problems-persist/
