A single dead pixel is pretty hard to notice on the rMBP. Chances are that it is multiple dead pixels. I love my machine but it's going back at some point because it has what seem to be 3 dead single pixels, a couple doubles, a quadruple, and maybe an octuple. Only the two big groups are noticeable during my typical workflow.
