This approach shouldn’t be specific to one container. Whenever the correct DV profile is included in the files encoding and container it should work.
With the correct settings made Plex HTPC just plays the DV file as a HDR10 file. This works as long as the backup HDR10 layer is included in the File. The DV layer gets ignored in this case though.
