Um, not yellow colour reproduction, but blotches of yellow extending from either one corner, or one side of the screen.
I had one good iPad out of the 8, and it had a large noticeable particle in the middle of the screen.
And if you're just trolling me, 6 of the eight were replaced over the phone so I had no choice but to take what I got. Then I did give up and accepted it, until now, which is why I'm selling it to pay for my mini.
If I can with all certainty, say that my iPad 2, and iPad mini screens are perfect, there is definitely a problem with the retina screens.
