I think it the picture is an optical illusion. Because the phone is lying at such an angle, and a flash was used, you are seeing the inside of the screen. In the 2nd screenshot posted by em2y0, notice the white square. The top line is straight, where the bezel, and the screen meet. If the screen was recessed, this line would actually be lower than the line on the bezel. The screen on the Hero is flush.
