There has been some extremely interesting development regarding Dolby Vision. With makeMKV 1.15.1 the developer added DV support for .mkv.
"While not announced on release notes page, MakeMKV 1.15.1 (released 15.4.20) should correctly recognize and preserve Dolby Vision streams in MKV file. "
“Dolby Vision is not a separate codec, but rather a (HEVC) stream extension - DV data (EL+RPU) are encoded in separate NAL units, according to Dolby spec.
The presence of DV data can be checked by several different methods - most obvious are:
(1) DV descriptor in codecprivate data (there is an “standard” of storing additional elements in codec private for AVC and HEVC streams, that was used for ages since 3D MVC video) or
(2)presence of DV RPU unit in first frame.”

And feature request for the mkv format:
It would be really awesome if you could implement this. I’m happy to provide sample file(s) if needed.
