I said yes. but i can see that there is a difference between what other people call perfect, and what i do.
on mine, the backlight seems less bright on the outer edges of the display . so when reading a book, i see (exaggerated), dark, light then dark again.
but then I dont think it's a backlight issue as if i tilt the display a certain angle, the 'darkness' goes away. so it must be a viewing angle thing. hence, the limitation is on the inherent technology and for what it is, it's perfect. no dead pixels, no image retention.
for kicks i turned off the light in my toilet once while i was dropping some serious log and so needed ipad as on seat entertainment. the backlight wasn't even if i turn the thing up to max brightness and made the screen all black.
but i wont ever see this situation in real life. so doesnt bug me.
i do miss my old screen however (iPad 3) the thing wasn't as warm and seemed more neutral. but thats again, by design.
perfect ipad 4 screen. 1 for 1.
