Default [Q] Black on high brightness seems purple

A few days ago I received my ONE back from repairs. I had the purple tint camera issue. I am not sure what happened, but first of all I noticed a stuck pixel when turning on the camera and covering the lens. I didn't have that before. Another I noticed, which seems strange to me, is that on high brightness black seems to have a slight purple tint. I put my old sensation and a tablet beside, it just doesn't look like black. Unfortunately, I know no one with an HTC one to check.

Can you guys tell me how your black is on high brightness? I'd appreciate it. I had to wait 3 weeks for the repair and I am not really in the mood to send it back in.
