yes sir, that does look bad. looks like you got yellow "glue" and flashlighting on the bottom there. honestly, you don't really need a black image to see it, if you notice it in a youtube video or something, then i would consider making a trip or giving apple a call. just my 2 cents.
It's miss
After thinking about it, I'll rather stick with it because I could end up with a worse copy and not be able to exchange that one. 25 % brightness is bright enough for me and I really can't see it there, but I listened to your advice and watched a few YT videos at a higher brightness and didn't notice it either, thanks anyways. Maybe the photo over exaggerated it.
