Im saying the orange/yellow is normal because I use night shift , but the red hue on top isn't .
Ok I understand what you’re saying now sorry about that, I’m gonna try to take a pic as well with my Night Shift on at full brightness but it’s still morning here I’ll do it later on in the evening, I really don’t remember my display looking like thatbut we’ll see later when I try. What does it look like when you don’t have the Night Shift on?

no need to apologize

without night shift it looks fine, a bit of a hue at bottom though, but nothing at the top (unlike in this pic). it annoys me but not the end of the world

what is it you see on my picture aside from the yellow tint on the whole display ?
 
I did some research on OLED panel manufacturing over the weekend, and there are some interesting differences between how Samsung Display and LG Display build their iPhone panels. The TL;DR is that:

All iPhone OLEDs are cut from large mother glass sheets (typically Gen 6, about 1.5 × 1.85 m) on which dozens of panels are deposited at once. Slight temperature and deposition-rate differences across that sheet make center-cut panels slightly more uniform than edge-cut ones (see Jeon et al., J. SID 24 (8), 2016). Apple doesn’t “bin” screens by supplier or storage tier — every panel that meets its ΔE < 2 white-point spec is calibrated and installed on the same production line (DisplayMate, 2023 iPhone 14 Pro Report).

Samsung and LG both use RGBG (Pentile) OLED structures, but their optical stack tuning differs. Samsung’s M-series panels employ a narrow, tightly tuned microcavity and a multi-layer birefringence compensation stack (Lee et al., SID 2019) that slightly over-corrects red + blue to suppress the usual green-cyan shift, which can make whites take on a faint pinkish hue at wide angles. LG’s C-series panels use a broader resonance cavity and thinner compensation films (WO 2019/200935 A1, LG Display) that favor higher luminance and warmer on-axis whites but allow a mild green/cyan shift off-axis as red light falls off faster.

Both designs are trade-offs, not quality tiers. Apple calibrates every panel’s white balance, gamma, and uniformity in firmware and adds True Tone compensation on top, so day-to-day color differences are within measurement noise. The remaining variance — cooler vs. warmer whites, slight pink or green tint at an angle — comes from variations in manufacturing physics and the fact that the human eye is most sensitive to green luminance (Fairchild & Wyble, Color Res. Appl., 2010). Every iPhone display is meant to be built to the same standard, but each carries its own microscopic optical “fingerprint” — the panel lottery is real, just not a matter of better or worse.

I have pages and pages of notes on this, if y'all want to take a deeper dive, just let me know.

So RGBG, additional green subpixel = green tint.

LG GH3 here on a 17 Pro Max. Screen looks great, there's no color tint any from wider angles that I could discern so far. Maybe a slight brightness dip but that I would expect. Will update this if I notice any anomaly that jumps out.

It'd be nice if the screen maker was consistent between all units, but even then the occasional manufacturing batch could have a defect that wouldn't be in preceding or succeeding batches of the same brand utilized.
 
Some data points (all with true tone/night shift off)

17 Pro Max (Silver 512 GB): G9N, top 90% of the display was almost a neon green, bottom was pink tinted - even at full brightness with TT/NS off there was a noticeable color and brightness gradient between the top and bottom

17 Pro (all Silver 512): all G9N
  1. one was similar to the above
  2. another had green tint of the top 60% with red tint on the bottom 40%, the left edge and top edge also looked blue & were noticeably dimmer when the screen brightness was lowered to 50% and below
  3. one had pink tint throughout the entire display and while this was more uniform, it wasn't as bright as the others & the camera was considerably less sharp (which is an issue that some phones unfortunately exhibit)
17 Pro Max (silver 1 TB) - GVC, green tint when i tilt the bottom of the phone away more than maybe 5 degrees but otherwise seems uniform and bright, will have to give this a spin for a few more days - so far looking better than any of the Samsung screens I have had. the lack of consistency in these displays is very annoying
 
I just bought a silver 17 pro 256gb and the raw-panel-serial-number starts with G9P. Has anyone had that one before? Is that good? I am PWM sensitive so I will try it out, was hoping for an LG display as I heard more positive things about those in regards to PWM.

I have G9P as well on my 17PM, it's a Samsung panel. Mine is as good as I'll find I think. Very uniform just a bit uneven toward the bottom 25% of the screen, but no pink tint. I don't think there's any difference in PWM settings between Samsung and LG, as the settings are tuned by Apple.
 
Another Sky Blue 512 GB Air, another GVC panel with green shift. Can’t catch a break.

I’m gonna have to wait for some money back before I order again, because I’m several thousand euros out of pocket here and starting to worry I won’t get it all back.

So here’s my most recent Air, GVC panel according to sysdiagnose, not that I care what it’s called – I just don’t want this green shift.

hWSAa3.jpg


Uncropped and unprocessed photo taken with my 13 mini main camera (26 mm-equivalent), obviously from fairly close (about 8 inches).

The camera’s auto white balance made the top look magenta as it tried to compensate for the green bottom, but in reality the top was still pretty neutral at this angle and the bottom was even greener.

Ignore the PWM banding from the 1/266 s shutter speed.

This really doesn’t work for me, for the way I use my phone.

I don’t care about absolute neutrality or perfect evenness at a perpendicular viewing angle.

But I can’t stand this strong green shift that comes on so abruptly at a specific viewing angle – the exact angle at which the words “Night Shift” are being viewed in this photo.

I’ve got a G9P on my regular 17. it’s the best display I’ve had so far on an IPhone. No off axis tint at all and a completely uniform screen.

Yeah that’s awful. Sorry you got that unit.
 
I bought another phone today. My GH3 with horrible green shift at 5 degree tilt is on its way back. The new phone is a 17PM Blue 512GB. The other one was 256GB. The new panel is a Samsung G9P. No color shift and no pink. The screen is even. It may be a hair warmer than the GH3. Very happy and can end this.

Thanks for the photo reference! It looks like it's happening to multiple panels, not just "the worst" LG one.

Mine (GH3) does have a pinkish top (1>3rd screen) and greenish bottom (< 1/3rd screen) and whitish middle. About 35% brightness. It's very slight, and only from a certain angle is it prominent enough to notice to the point that something's not quite right. For the angle when noticing it, the top is a couple of inches farther away from me than the bottom and the phone - overall - is a foot away from my face. Other angles weren't as bad and I don't think I'll notice under most general uses, but I don't do work that's color-sensitive on it. Some people will and it's an important requirement.

My 17PM is blue, 1024GB storage, built in August, will have to look up the actual day.

At least it's not from the days of the old TN panels, yuck... but, yeah, if some models are consistently hued at any angle, then why introduce another brand panel? (It sounds like LG is better with PWM but Samsung is better for hue uniformity?)

That is EXACTLY how my GVC Air and GH3 17 Pro Max looked… Return that ****.
 
My second Air also has GVC. Colors, uniformity and shift all seem ok again. Grain still present and noticeable, but better than the first. I'm still annoyed by it, but I don't know if it's worth the trouble of returning again.

Exactly how it was for me. Had a 16PM with GH3 display before.

Me too. And I guess thousands of users outside this forum.

Poor uniformity and color tint has always been the indicator of a no-no panel. Until now.
I had similar with 2x 11” iPad Pro M4. One from Apple and one from Amazon. The panel on the Amazon device was horrific with at least 3 colours across the panel. I returned it and kept the Apple one despite the Amazon being £250 cheaper.
