I was able to find a reason why some HDR TV issues happen, when others are not. I found out by accident why my TV is not affected by washed out look. I noticed in the settings, HDMI black level. In factory default, which is commonly used in calibrations. You limit black level down to 16. HDR, THX, and PC requires black level down to 0. The setting may be listed as low, wide, full, or even PC.
also my TV has a PC only connection. Which allows fractional and undocumented resolutions. PAL and ATSC can coexist without any setting other than seletting HDMI 3. Well any way, wash out comes into play when HDMI black level is not set to 0. If you are willing try adjusting that to correct the box HDR wash out ofor colours and blacks.
here is a link to a site that explains what I wrote and lost before submitting.
