I will, but unfortunately very busy, that's a quick one for the image quality I've taken on iphone 8 - don't take it too seriously but obviously you can appreciate how the image looks. 

You didn't mention what the color space and bit depth was set to on the X9S and Lumagen Radiance Pro.

I don't see much banding with this clip on my Samsung MU8000 UHD TV. The one scene that I do notice it is around 1:54. There are other movie scenes where the banding is more apparent (The Martian, The Revenant). I have to check the Peanuts movie that @lionne has mentioned.

In the past, I have said that this is mainly a display processor related issue. I am having to reconsider that thought. On my Samsung TV, I get severe banding with 12-bit YCbCr 4:2:2/4:4:4 inputs from the X9S, but I don't see that with the nVIDIA Shield or Apple TV 4K both of which outputs YCbCr 4:2:2 at 4K 24Hz. It looks like something is not right with Zidoo's output.
