All iPads Backlighting issues?

my 4 is brighter on the left hand side. im having it swapped out (for a different reason today) so will see if the new screen is any different.

 

when you swap it within 1st 14 days do they swap with brown box swap ones, or directly swap it with white box(with all accessories)?

 

Had 2 iPad 4 already, both uneven tint. Not impressed.

Bought in store: good chance to get a new boxed one. Bought online: probably brown box.

Doesn't matter, they're all brand new at the moment.

 

bought it online and the replacement came in a new sealed retail package. screen is shocking in this one oh well.
