i noticed that the blurred background of my sleep focus home screen has a weird dark area in the upper right corner of the screen, where the dim is more intense than anywhere else on the screen. this does show up on screenshots, while other pictures and the screen without the sleep focus blur look perfectly fine. so i’m thinking this probably is not a hardware issue? you can hopefully see what i’m talking about in the picture. the green tint is from my usual phone background, little black area in the middle is black text.

to get it out of the way: i have recently had my screen replaced on my iphone 12 by a non-authorised third party repair shop. i cannot afford official apple repairs atm, so i went with a reputable repair guy in my area. it’s not an original apple screen. the screen is working perfectly in all regards except this one, so what i’m asking is if it’s possible this is actually a hardware issue with the screen, or if it’s some kind of software problem? do i contact the repair guy? is there any way to fix this?
