Hello, I'v recently had my 2012 rMBP 15" screen replaced via a mail in service as I bought it from Apple's online store. It took 8 (business) days for the repair and as soon as I open the lid, I saw that it's at least 2 'notches' dimmer than my previous screen (which had dead pixels and image retention). The replacement also has yellow tint which further accents the dullness of colours etc. I called apple (senior service) and they told me that I need to send it away again to have the claim verified. They said that this can take at least one week, but if the claim is confirmed under UK consumer law, I can get a repair, replacement or refund. The rep. said the AASP will run a diagnostic test and it comes back 'clear' I might be charged! I stated that there's nothing actually wrong with the screen, it is just quite different to what I had replaced. I mentioned that this is a very subjective matter and the service provides are probably replacing the screens with the same colour and brightness, so to them, it will look fine. (I doubt they will remember how it looked before). Has anyone else gone through this recently? Part of me just wants to send it away because why should I settle for something less? But I just have this huge feeling that the service provides will not be as bothered about the variation, since they aren't the one using it all day... It's just so frustrating because it could just be a complete waste of time.
