I just got hold of a brand new mid 2015 15" base model rMBP and the first thing I did was to check the screen uniformity, white point and IR test. The panel is an A02E and it has IR when the 10 minute checkerboard test is run. The screen is uniform and ok in terms of white point but I don't think it is as "snow white" compared to the units that they have in store. I have not found much info on the A02E versus A02F 15" screen debate but is the A02E panel inferior compared to A02F? It was bought from an official Apple Store but the return window has expired by about a week. What is Apple's standard practice on handing this? Will they replace the entire laptop or replace the screen? If the latter how long does it normally take?
