What is this ugly thing on my 8K TV with HDR only content?

-I have a Samsung QN800A 8K. 
I've followed RTINGS recommended calibration settings (for SDR + HDR), to try get the best out of my TV.
-My HDR settings are here.
-I use a 4K Firestick (2020 version) and watch my movies/series through Stremio (All 4k content, both SDR and HDR!).
-I do not use any native/inbuilt Samsung apps such as Netflix, Disney+ etc.

The issue
-With HDR content, some dark scenes (as I've come to the conclusion it's dark scenes only) suddenly have this 'grey film/haze' over the scene. Then it switches back to normal.
This Video shows the issue in action!
-I usually watch content in a dark-ish room + as HDR was initially too dark (as is generally), I had to bump up ST.2084 Gamma and Contrast Enhancer (which improves darkness).

-I've looked up so many terms, from Banding, to EOTF tracking and Contract Enhancer, thinking each time that that is the cause/issue, but I find out it's not quite that.
It seems that reducing 'Local Dimming' kinda makes the 'grey film/haze' disappear, but then the scene is too dark again.

Going forward
-My TV should still be good enough for HDR content right?
I'm now at a dead end as to what else I can do.

Please can you share any insight into what the case is, what the name of said cause is, and how the hell I fix it!

Thank you, this is my last hope!

I don't think you're going to get detailed help here. An AV forum will be better https://www.avforums.com/forums/samsung-tvs-forum.145/

Personally, I would NEVER buy an 8K TV (just bought a 4K 75" Samsung) because there's very very little 8K material so the TV is always going to be messing about with the image to make it 'better'. I still buy 4K Blu-ray too so it's pointless.

I do like YouTube but 8K material is very limited so that's no big loss.

I've turned off/down anything that could mess with my picture although it's fair to say there's less TV motion 'effects' on my TV than the previous 2.

ha I've asked exactly on that forum but no replies.

We bought this becuase it was a display TV in amazing discount (along w/soundbar), so as a package I guess.

Ah. Well, all you can do is change the picture setting (eg Game Mode etc) to see if it lessens the annoyance which looks like a feature and not a bug unfortunately of your attachments .

I turned all (AFAIK) HDR settings off as they're either too filtered (like a veil over the whole picture) or the effect of the HDR setting does something I just don't like. That's just for YouTube incidentally as for my UHD Blu-ray I've not watched enough on this set yet to assess exactly what I don't like. And I will dislike something which seems to be the norm.

I mind looking at the 8K reviews and I was put off because I'd rather the TV NOT process to death my picture especially native 4K Blu-ray.

The "Settings" button seem like a torture device nowadays.

bumping again till I can get some technical/engineer type help from anyone on the Samsung community.
If there are no AV people here, I might just leave it once and for all...
