I have an approx 1in spot on my iPad Pro screen which is brighter than the rest of the screen - it's unevenly lit. The spot is about 2in above the home button, and although it has soft edges, I'm anal about my gadgets, and the difference in brightness could be described as 'minor', it's clearly there. It looks a bit like a pressure spot or similar. I always keep it in a case with a screen protector and the Smart Keyboard, so it's well looked-after.
I can't find much about similar issues online - anyone heard anything similar? I have a Genius Bar appointment later in the week to see what Apple think (spending £800 on an iPad means I pretty much expect it to still be perfect within the warranty period).
