Hello! It's been a couple days since I received my macbook pro 2012 with a matte screen antiglare. I work with CG and photography. Unfortunately, I noticed that when the background is black and the brightness is high, I can clearly see a dark burn/smudge/stain on the screen. I attached some photos taken with my iphone, it's not easy to see but should give an idea of the issue. However, it is fairly easy to see it in person. Do you think it's supposed to be normal? Should I contact apple and try to exchange the screen under warranty? Thank you for your time!
