Yep get a 11" pro best iPad ever and no back light bleed, i gave up on those iPads for that reason, also white spot on 10.5 and red/majenta on the mini.
You could swap 10 times before you get a good one. If you use it for video in dark you will hate it.
I don't have the financial resources to purchase an alternative ipad. This one's still on contract with EE.
I've been back in touch with Apple who've requested I return the replacement ipad. I've requested that they check any subsequent replacements for backlight bleed issues prior dispatch. Otherwise they're just wasting my time.
