Apple's warranty cover dead pixels on iPhone 4S

I received my iPhone 4S in the mail today and a few hours after I had been using it I noticed a tiny dot on the screen. At first I ignored it, thinking it would go away, but it hasn't. I searched what the problem was and found out it is a dead pixel. Like I said it's very small but it really bothers me every time I watch a video or take a picture. If I take it to my local apple store, will the warranty cover this?
