Talking about Netflix, it uses HEVC 10bit for 4K/HDR streams with highest HW DRM possible and the system doesn't offer any other codec for such content .
So, Netflix is already on the boat of HEVC 10bit since the beginning of 4K in 2014.
The artifacts I'm talking about have nothing to do with low bandwidth or codec of 4K content, but with the change in encoding type as Netflix mentioned in its article.
As I said before, the problem is not low bandwidth by itself but the way Netflix is trying to handle it using the "optimized" techniques of 4K re-encoding during the last few months.
