iMac 27" 2011 stuck pixels or what?

I noticed few pixels with strange behavior on my iMac 2011 yesterday. In the centre of the screen one, or few pixels act very strangely. They are dark, or dark grey when you look at them at one angle, but when you move your eyes that issue dissapear. That pixel is white, or dark grey or normaln color depending on viewing angle. Unfortunately this is not a single case. I notice maybe 3 pixels on screen with same issue. It's not really obviously except you focuss on that area of screen. Because of that, I pretty sure that pixels are not dead. Maybe they are stuck, I don't really know. It's important to say that they change color when you change viewing angle (just move head a little in one side). What could that been?

That sounds like dust or some sort of debris. Damaged pixels wouldn't adjust according to where your eyes are.
