Can you take a comparison picture with a camera?
Are the colors washed out or too dark?
That is kind of a contradiction...
In the "mm" build the colors are not consistent. Sometimes, on a given sample clip, they are normal, sometimes washed out and sometimes overly saturated.
I've played several HDR and non-HDR HEVC Kodi sample videos. Sony's HDR Camp clip, for example triggers the oversaturation on other (Patagonia) sample. If I play "The Life of Pi" or Astra's video — they restore the colors to normal.
Sometimes Sony's camp looks more realistic and sometimes too reddish, but the HDR effect always presents.
