Banding while playing UHD BDs on a Samsung UHD HDR set.

I have a Sony UBP X-800 UHD BD player and a Samsung UE49KU6400 (European model) 49" T.V. set.
While I was watching War For The Planet Of The Apes today I noticed some banding on scenes. It's a dark scene when Cesar and Woody Harrelson meet. Harrelson has some windows where light comes in into the dark room, when Harrelson gets a camera close up the light that comes in by those windows shows banding/posterization because of the different shades of white/light grey.
I checked a similar scene on the UHD BD of Prometheus, at the very beginning when Shaw is showing her discovery on the cave to her husband with a lantern. The light from the lanter also shows some banding/posterization.
I'm sure my set uses an 8 bit pannel but Samsung advertizes it as HDR with Wide Color Gamut, this set must use video dithering to simulate WCG.
I tested these scenes with both 4:2:2 and 4:4:4 component video and the result is the same.
Is this normal? Do HDR sets that use 8 bit pannels with dithering show banding at more or less the same level as an 8 bit HD video signal coming from a BD?
The Sony X-800 player is connected to HDMI por 1 which is the only one that accepts 4K HDR signals and I have "HDMI UHD Color" enabled so everything seems to be set up right. HDMI cable is a 5 meters Amazon Basics which is said by both Amazon and reviewers to pass 4K HDR 24p video signals. My older Monster Cable 5 meters HDMI cable was unable to pass the 4K 60p signal from the X-800 menu, I've never experienced a single glitch with the Amazon Basics HDMI cable.
It's not that I'm seeing banding on every scene and neither it bothers me much but I'm curious about this issue. Maybe what I'm seeing are compression artifacts and not banding.
What do you think about this?

Likely limitations of your tv. Those fake hdr sets aren't gonna give great results.

I would explore the AVS forums where your specific TV is discussed to see if there are any setting recommendations you can try. You can also directly ask a question there, too. A number of owners of this TV have posted their settings.

Thank you both for your replies and the link which I'm sure I'll find very informative and useful.

Hello, I had the same issue. The new player I bought had a deep color setting that I changed to “10 bit priority” from “12 bit priority” and it solved the problem completely. I found this because the menu actually said “if the banding noise appears, please try 10 bit priority”. So as far as I can tell it’s entirely a deep color issue; if you can change the deep color settings on your player that might fix it.
