I think I can confidently say that these are not heat-related either - mine was apparent straight out of the box. If anything, the longer it's used the more apparent it becomes.
As others may have done so, I would recommend downloading a flashlight app to be able to see how bad it really is. I was worried the Apple staff at the store might laugh at me and say there is nothing there as can be a little hard to make out in regular use - but the discoloration is plain to see when I use the app.
I'm going to swing by the store this evening after work and hopefully the hoopla has died down a bit, and given the supposed stock levels, hoping they will be able to replace it then and there. Hell, not hoping, they HAVE to. You don't pay top dollar for defects like this.
