I just used sysdiagnose, and my display is a G9N. What does this mean?

tWhere did you get the info in Sysdiagnose? I ran it, but there is a lot of files.
Thanks.
It's in the file called "IODeviceTree.txt" and search for "raw-panel-serial-number"

Wait so maybe this is a thing! Because mine is tinted warmer on the right side.

Guessing perhaps some tint variation is within spec of G9N, or such changes per year or screen tech generation, or something.

Also have a G9N and it seems great. I’ll possibly later compare with others. I recall others in this thread or elsewhere mentioned some codes that seem not mentioned elsewhere with the impression that they were possibly better, perhaps new.

I pre-ordered two for launch day which I always do. One delivery and one in store pickup. If the delivered phone is good I just cancel the store pickup.

I got lucky on Friday and secured one for pick up at a local Apple Store tomorrow. I had the app and website open at same time and saw green in stock and pounced. They only last for seconds when it shows in stock.

Got lucky this year (don’t normally) and got a Pro with a screen that is completely even and has no colour cast at all, greyscale is perfect at all brightness levels too. Must be from close to centre of the wafer.

Those 15pro and max users, how are you guys having luck with screen uniformity and color cast? My uniformity looks good in 15 pro max but the color cast is more yellow compared to my 14 pro . I have to turn off True Tone. Wondering those upgraded from 14 pro see similar? Love the size coming back from reg pro but the color cast is a bummer!
I have not noticed this as it does not impact me much. Do not overthink it. Is this color cast issue a big deal or a deal breaker for you? if it is, you may want to return to your 14 pro. If it is not, enjoy the new phone! 😊

Probably gonna return my 15 Pro and play the lottery again. With night shift on the tint is so green its distracting, especially compared to my 14. Honestly the lowest quality display I’ve ever had in an iPhone - pretty ******. Hoping I just got a particularly poor one and the next ones alright

Just picked up another 15PM to compare. This one is perfect. Perfectly uniform screen and no tint / hue issues in normal light or dim light / night shift. No pixel issues, no dust, no dings. Slapped a screen protector on and transferring my data now.

Don't settle / let Apple run with your money when it comes to screen issues. I've used $400 phones that have perfect screens, there's no excuse for Apple.

When I was having heating issues with my 15pm the right side of my screen was noticeably warmer. Now that I’ve figured out what settings for the phone to keep the phone cooler, the uniformity is even across the screen. Seems that when my phone heated up, it threw off the colors on the screen.

Which settings?

Bought another 15 Pro today to compare with my current one.

Night and day difference, noticed better brightness straight away during setup which wasn't even an issue before. Whites were much better too. Stuck it on night shift and compared both in low light. The new one is much better, really uniform. There’s still a degree of greenish/yellowish tint to the display. I think Apples tuned the display colours compared to the 14s.

Highly recommend returning and trying another one if you're experiencing this.

EDIT: Will check which panel I have on this new device tonight and let you know.

I had essentially perfect uniformity on my 13PM, had to return 2 phones to get a decent 14PM, and got an essentially perfect 15PM first go.

I have a seemingly perfect G9P display

Is there anything that officially documents that the 3rd character somehow implies a quality grade and not just some other aspect of manufacture?
How did you know what type of display your device has?

My new device is G9P as well... I think the theory about G9N being the best display doesn't mean anything. Seems like a lot of the G9N's from the 15's are less uniform based on this thread

I have iphone 15 pro and 15 pro max and both are almost the same.

Both with G9N screens and the Pro is perhaps slightly brighter at maximum brightness.

I must say that if the phone is hot, working or downloading to iCloud, the maximum brightness is reduced. This must be taken into account to make the comparison.

Screen uniformity has to do with where the OLED substrate was cut from in the wafer not who manufactured it. Photolithography is (as far as I’m aware) the same for all the suppliers of high end mobile OLED screens. If you are lucky and get a screen cut from the centre or reasonably close to centre the screen will be even. As you move further out from the centre of the wafer the uniformity becomes worse and those from the edge of the wafer will be the most uneven.

You’d think a company with the resources Apple has would only use the better quality “cuts” / have stricter tolerance for a $1100+ phone. I guess not. Need to cut costs somewhere, it’s the Apple way.

100% , I cannot wait until the next display technology is used for iPhones. Perhaps in 4 years time?
