Put a ruler on the screen to see if the surface is actually flat. Then
see if straight lines in the image are straight (again using the
ruler). If it is flat and the lines are straight then it is an optical
illusion.

I know there are standards for the number of dead pixels allowed, but
what you are describing is a pixel where all three colours are dead
which I think is unusual. Check the standards to see whether that is
allowed. My screen has one pixel that shows the wrong colour as the
two other colours still work and it is only noticeable if I look for
it.

What is the native resolution of the display (in pixels) and are you
running it at that resolution?
