Both touches I've gotten had multiple dead pixels, I looked at all the touches on display at two separate Apple stores, again all of them had multiple dead pixels (12 touches total, 14 including mine). They are a slightly greenish color and appear primarily over very dark or solid black colors. You sometimes have to angle the touch to see them. I'm not sure I'm convinced any "perfect" touches exist. The dead pixel problem is massive with these things.
