iPhone 15 Pro iPhone 15 Pro - grainy screen

[Gameboi301123]

Saw this grainy mura effect thingy on my 15p, got a screen replacement from the apple store under warranty. It hasnt fully gone, but it is wayy better now. Like its gone down by 70%.

most displays seems to be having this to some extent this year (this was tru of iphones 13 and 14 too) For the devices on display in the apple store , a couple pf those had it too. Most people don't notice it so maybe we’re all just geeks haha.

For those who may concern:
Here is what i found (i have swapped more than 5 units and observed 20+ units at Apple Store)

iPhone 15 pro series use display from Samsung and LG.
In terms of display part code:
Samsung: G9N G9P G9L G9Q
LG: GVC GH3

Usually, Samsung displays have a greener color tone and more aggressive color shif at angles, while LG displays have a reddish color tone and alot less color shifting at angles. As the pics showed below.(LG GVC on the left, Samsung G9P on the right)

Also, most of LG displays have the “grainy paper texture” issue.(I have seen multiple LG displays have this problems)

Thanks for the info, but since you find out which manufacturer the screen is, you use an app??? There is a log on the iPhone that identifies her???
