Looks like this is still a problem even with the newer screen lamination process. Just noticed upon startup that the bottom left and bottom right corners of my screen have this smudge/streak/smear sort of appearance going on. I used the provided cloth to clean the screen (no harsh cleaners) and as expected it didn't do anything. My apartment is very clean and I run a tight ship, especially around my Mac. I keep everything very clean. Alarming to see this happened, assuming its related to dust or something like that. Since I imagine the screen needs to be ordered and this will be a few days for turn around time, I schedule an appointment Monday evening so I have my machine for the weekend to get some work done. Will report back with what Apple says or does. Unless anyone knows whether or not they keep 27" screen on hand for fast turn around times? The Apple Stores in North Jersey are always bursting at the seams with people, so they're certainly busy stores - would imagine them having a decent amount of parts available. Pics below of the bottom left corner taken with an iPhone 5s, so it isn't doing it much justice. Same issue at the bottom right. In person it is a lot more noticeable. Overall, the screen has had fairly inconsistent lighting resulting in some areas darker and cloudier than others with a white background and of course slight yellow tint. Honestly, if I get a replacement as good as this screen (minus the weird conner smudges), I'll be happy. Too many horror stories of people getting replacement screens with dead pixels and or extreme yellow tint.
