iPod touch iPod touch 64 gb screen color nonuniformity

[Eggman32]

Hey everyone,
I recently got a 64gb touch with my new MacBook pro, I've kinda noticed a "nonuniformity" with the colors on the screen. I've noticed the bottom of the screen to be more yellow than the top. This is more noticible with whites and Greyson on the screen. It doesn't look too bad it just seems weird that the same tone of white doesn't look the same on the top and bottom of the screen. Is this normal or some type of defect? I don't know if it's worth exchanging or not...

I personally have not heard anything about this so it might be a defect, but if its not that big of a deal then theres probably no use in exchanging, because of shipping and such, but you might want to call apple or something
