Injecting DV (8.1) and HDR10+ to the same video

[fabiov64]

I'm processing and delivering videos using DaVinci Resolve Studio and I've the possibility to generate both DV metadata (xml) and HDR10+ (json). I'm using dovi_tool for injecting DV (8.1) metadata and hdr10plustool for the HDR10+. Usually I mux the audio and video streams using mp4muxer.

I'd like to understand how can I inject both set of metadata, obtaining a file compatible with both DV and HDR10+ and eventually how to mux with the audio (if mpeg4muxer cannot tag the output in the right way). I tried to inject DV and HDR10+ metadata but after muxing with mp4muxer or MKVToolnix the mediainfo reports only DV profile 8 (not 8.1), without any HDR10+ mention
