Apple Repair Service Image of cracked bezel -or- what am I looking at?
As far as I can tell from the blurry picture, it seems you're looking at the display itself and the bezel that surrounds it. If you look at the lower, right corner, you'll see that the bezel is cracked.
Was the bezel cracked before you sent it in? - If so you had this pre-existing damage that you probably didn't declare.
If the bezel wasn't cracked when you sent it in, it was probably cracked during transportation. You should inform them of this to see if there's an insurance or similar that covers such an event.
