I bought a Hisense 65 Q8G on Black Fridayand it's mostly been great. When Lord of The Rings was remastered to 4k I bought the 3 movie box set on Google Play Movies and 1 of the 3 movies I would experience the black bars switching from a true black to a dark grey continually, very annoying. And there was also some horizontal noise along the bottom of the screen. Since I bought on Google Play I also tried playing them through the YouTube app and they were fine.

I figured it may just be an app glitch with Play Movies.

Now I'm watching episode 8 of Wandavision on D+ and it's doing the same black to grey bar issue. 4k Dolby Vision.

I don't have any display setting turn on like auto detect contrast, motion smoothing/enhancement/clearness, etc. None of those

All apps are updated as is the TV. I did an uplug power reboot and still experiencing the issue.

Any ideas or solutions?
