TT on will have a yellow tint even if your iPhone has the best calibration in the history of the earth. This thread is for people with yellow tints with TT OFF and Night Shift OFF.
Are you sure about that? Not so sure. I believe most people with the yellow tint have TT on. My 12 PM TT on and off.

Exactly. The funny thing is, if you turn TT on and flash a decently bright blue LED on the light sensor (like from a flashlight) you can make the screen look bluer than with the TT off. Otherwise under regular incandescent lightbulbs TT looks way too warm.

Maybe software calibration can address this.
Excellent description. My 12 Pro Max screen looks better and more accurate than any screen that I have when it is in bright blue lighting conditions with True Tone on. Not in other conditions, unfortunately.

Hi. Yesterday I received my iPhone 12 Pro Max (pacific blue) and is exhibiting the same issues as described in these forums. The display is warmer/yellowish/dimmer than my iPhone X. Also, the whole screen flickers dimly in black areas where the pixel are supposed to be off on video and pictures. So, I called Apple and initiated a replacement process but, I am kinda expecting to receive a new iPhone with similar problems since all my friend's new iPhone 12 pro, are confronting the same issues after testing. Some of them didn't notice the issues but after the tests, well, nobody is pleased by it. So my question, should I keep it, replace it, or returned it and wait until the issue is resolved? Is there any fix coming soon? is this issue fixable? My 2017 iPhone X display looks greater than the 12 Pro Max.

For the record, my iPhone serial starts with F2LDN.

Woot woot! I think I got a good one boys! Now calm down a second... it still has a 6500K color temperature and would still look warmer and perhaps a bit more yellow than many iPhones from previous years, but it has noticeably less green tint than my first one, which was my biggest issue.

The touch screen was acting up on my first Pro Max, so I went in to an Apple Store and swapped it out. I obviously don't have the first Pro Max to take side by side pictures, but I do have colorimeter measurements for both screens.

Average ΔE / Color Accuracy - lower is better, < 2 is considered good, < 1 is considered excellent
  • Original F2LDN / GNQ Pro Max: 0.99
  • New G0NDL / GN9 Pro Max: 0.82
Average Color Temperature
  • Original F2LDN / GNQ Pro Max: 6521K
  • New G0NDL / GN9 Pro Max: 6518K
Now, the average color temp is almost the same, but I noticed that DisplayCAL shows a much higher error in white point / color temp for my original Pro Max, and I suspect that's because it had so much green tint.

Measured vs. Target Whitepoint (sRGB 6504K) ΔE - lower is better, < 2 is considered good
  • Original F2LDN / GNQ Pro Max: 4.02
  • New G0NDL / GN9 Pro Max: 2.34
RGB Gray Balance

You can see that there is still a slight tendency towards green in the darker grays, but it's a lot more balanced and less green looking than my previous Pro Max.

Gamma - Should be 2.2 all the way across. Ignore the empty target circles as that's the original sRGB spec meant for CRTs, and most modern displays aim for a flat 2.2 all the way across. Lower gamma will make things look more flat and washed out, higher gamma will look more contrasty.

I hadn't noticed until now, but my original Pro Max had an average gamma closer to 2.15, which is a little lower than it should be. I wonder if the people complaining of a washed out look have phones with gamma that is too low. My new Pro Max has gamma pretty much right on 2.2, which is better.

In the end, I'm a lot more happy with this display. I'm sure some people would still be unhappy with it because it has a 6500K color temperature, which is warmer than the displays in most Macs and iPads, and warmer than what most people are used to, but I can live with that since it's technically more accurate. I just didn't like the green tint of my first display, and this new one has a lot less of that.

edit: By the way, the original Pro Max had screen serial G9Q (Samsung bad) and the new Pro Max has screen serial G9N (Samsung good), so at least in my case, those good vs bad grades seem to hold up. Also, just in case anyone is wondering, the new Pro Max was actually built before my original. Original was 11/8 and new is 10/25. And they are graphite color.

I decided to keep my 12PM knowing that if I exchange it I will most probably receive one with the same issue...and the hassle to reconfigure it again.
Several option for me :
-Option 1 : I have until Jan 8th to return it.
-Option 2 : It is under warranty for 12 months and if any flaw is acknowledged I will ask for an exchange.
-Option 3 : SW fix, fixing the agressive TT and raised black OLED. Best option.
-Option 4 : If no fix and yellow tint really bothers me I will turn TT off and live with the raised black until the iPhone 13 is released.

Wow that is a lot better! Interestingly its not much difference in the whites, just the darker greys. Crazy that that small of a shift in green can make the screen look that much better.

could please share a picture of both with same settings?

i still don’t know what to do. :-(
This phone is awesome, but with the yellow tint...

How can I know which screen panel was mounted on my phone?

I don't have the old one. Traded it for the new one at an Apple store.

Well, to be honest, I'm very observant and tend to notice little things that other people wouldn't, so put it into perspective when you see me say it looks a lot better. A normal person would probably say it's only a very small difference, and if they weren't side by side, a normal person probably couldn't even tell the difference. And like I said, it still has a warm screen, so it's nothing close to the difference that other guy posted where his new Pro Max looks like it has a super cool color temperature.
 
Got my third 12 Pro Max. Slightly less yellow than my first. Slightly less green than my second. I guess I'll live with it.
F2DL with a 11/1 production date - which is a few weeks newer than my other two.

Exchanging at this point seems pointless. Either @Robita's cool screen is a miscalibrated fluke or cooler displays are not reliably circulated yet.
 
Hi Guys,

I had been following this thread and was concerned about screen issues. I had just received my I12 PM in graphite and I compared it to my oneplus 6 and a iphone X. I noticed that the screen was warmer and dimmer than the X. It was totally unnoticeable without placing them right next to each other. I was curious about something so I turned off Auto-Brightness and HOLY MOLY was the screen just SO much brighter and more white than the X and my oneplus 6. It started to burn my eyes, so I quickly turned back on auto-brightness. You guys should try turning off auto-brightness too and waiting 15 secs to see if it fixes your warmer screen issue :D

I think this thread is not for you. I understood that you have the following issues:

Issue 1: Raised blacks --> There is a thread specific for this issue.
Issue 2: Aggressive True Tone --> This has been noticed by many and should have its own thread as this is very likely to be corrected by Apple. If I'm not mistaken, the same has happened in prior releases (I forget which) and was adjusted via software update. No big deal.

This thread is specific for people who hate true-tone and night shift and always have it off and yet find that the 12 displays have a yellow tint, that makes it seem as if they had true-tone on (Issue 3). Unfortunately this is less likely to be fixed by software update and the issue get minimized by others as they think we are complaining about a yellow display while having true-tone on.

Trust me that 99% of the users complaining on this thread would love to be able to solve the problem by just turning true-tone off.

My experience is similar. Turning off auto brightness didn’t completely eliminate the yellow for me. It did make the screen overall look more vibrant. That’s with the brightness levels the same. My trick knee gut feel intuition is that auto brightness does more than just control the brightness level. Looks better with it off.

On the contrary, don’t most of us love True Tone but we’ve been forced to disable it because the base white level calibration is off?

I don’t think anyone here hates it generally, or night shift when they’re working as intended and at the right time.

Read my response, I'm acknowledging that it is an issue, but a different one. Based on what I've read on this thread, the true-tone on the 12 series is too aggressive, regardless of how good or bad the white level calibration is (good panel or bad panel). Someone who likes true-tone (I don't therefore it is not a problem for me) should start a thread on this topic. Who knows, maybe Macrumors staff will pick it up and make a story on this. They've ignored the yellow tint so far, so anything being said here has zero chance of being reported.

I have issues with getting these two issues blended as one as they are truly different.
 
How accurate is that good panel and bad panel table. I have G9N Samsung Panel. My display is warm. My display is green. My display got black flickers. When i switch off auto brightness off my display goes extremely bright. My display is defo not extremely yellow as posted by some. Im getting a replacement but in two minds now what if that unit is worse than current one. My partners Pro has G9Q panel and looks no different to my Pro Max.

I hate True Tone and Night Shift lol. They sounds great in theory, but looking at a screen with them on just looks horrible to me... on any device, not just the iPhone 12.
