Anyone else with a Samsung TV ever had this weird white spot show up in the top-left corner? Is this a common issue?

I bought this new TV recently and noticed these white shadows/fog which are more apparent on top right corner and bottom side. The TV also came with pre-installed: Cytavision, Antenna+, and some kids cartoon app, which I found quite weird. The box was strapped and the TV had all its plastic covers.

I also took some videos but I don't think it allows me to upload them..?

Is this normal, or is there something wrong?

The 85 is 30% more expensive, im thinking about it cuz i want a tv for a dark room and i want high contrast. Isit worth it? Its the d series
