Even if the data ends up in the file, no indication of this would be stored at the container level, there is no header element saying "This track contains Dolby Vision data". I don't think that this can be meaningfully extracted as a separate track (if it is shown as a separate track, then it is likely not stored in the video stream, so it has its own PID and one could "extract the track by using a PID filter).

There are 2 ways to store Dolby Vision. One as SEI messages in the base video stream. On Blu-Ray it seems they use a second "track" instead. As you say there isn't really any way to "properly" copy that into mkv yet.
