Hi, as I was curious I made one more test. I tried to mux into MP4:
I was curious if this can play at all
The effect is:
- Single layer DoVi track, taken from UHD Bluray with MakeMKV
- EL layer, (dvhe) taken from the same UHD and demuxed with ffmpeg into BL+EL

The effect is:
- nVidia SHIELD Pro 2019 plays it as Dolby Vision but it is stubborn to play for some reason the EL track so you just got Dolby Vision EL layer which look really strange
- Plex on C9 falls back into HDR - maybe there is too many dvhe streams in this MP4 file
