Well Alex why not just return it and let the ones of us that still have it post pics of what we see. Then we can see other sets views and make a determination. I can say it is by no means an Oled but it is better than any Samsung I have tested.
I can see also some of the things you describe but at none of those levels. I had a weird experience last night that blacks showed purplish but that was feed based for some reason.
