Not too sure what that is, hard to tell from a photo.
Definetly not dead pixels though as they would be black I.e. turned off, perhaps a group of 'stuck' pixels?
Either way, that bleed/glow looks pretty bad IMO.
I would try and get a replacement.
Edit:
Brightness setting?
The pic was taken with brightness at default so full i think.
And the screen bleed in the corners looks ok until i take a photo, so may be wrong cam settings. I will try get some better pic tonight after work.
