iMac 5K Late 2014 Dead Pixels

[1452983]

Hello,
Today I have noticed that some (thousands) pixels (pixels on the left and the right side) on my iMac screen are white when displaying black. I have checked that this problem occurs both in OS X and Windows, so it is not a software issue. Are those dead pixels? What do you think about it?

This goes from the very top of the screen to the bottom on both left and right side.

Is your iMac covered by warranty? If so, definitely worth taking it in.

I will call Apple Support tomorrow. That's pretty sad that it happens, because this is my second iMac - the previous one was replaced by Apple because of failing Fusion Drive.
