Also there are lots of possibilities under "Dolby Vision" most of which are very strange and would be impossible to covert to HDR10+ without some loss, everything except profile ID 5. There is probably something else about profile 5 that does not directly translate to HDR10+ too.

Definitions of Dolby Vision bitstream profiles on page 8:

Yes DoVi is very strange, if I read it correctly it can uses metadata (profile ID5 or ID8) or it can uses a FHD video stream (profile ID4 or ID7) as enhancement layer ?

Ok so if I want to encode a DoVi movie to play it on a Samsung TV (only HDR10+, not DoVi) I can't do it. The only way is to encode the movie to HDR10 and to lose dynamic metadata ?
