Kodi 21 support mkv Dolby Vision files LG G4, Denon X1800 running Shield Pro 2019



Hello all, my first post here, I’m thinking of purchasing the LG G4, my setup is Denon X1800 with Shield Pro 2019.
I understand that Kodi 21 supports Dolby Vision MKV files now, does this also work with Denon X1800, LG G4 and the Shield Pro 2019 with MKV remux files that I want to play via a NAS?
If so which Kodi version do I have to download to make sure this setup will do fine? I see different versions and types, sorry, but it is not entirely clear to me which version I should download where?

LG G4 also supports MKV files via the internal player of the LG G4 but not sure if it falls back to HDR10 and how can I be sure that if I play the mkv files , I will have TRUE HD or HDMA or Atmos via my Denon?

What do you recommend?
