timebeing if that’s your “playflow” then why not just download HDR10+, afaik all most hybrid mixes are st. 2094, which is the best case you can squeeze out of a dovi-incapable system with jriver???
And if one’s excuse is “future upgreadability”- if you haven’t got a DoVi system by mow, you probably won’t, given that Dolby are rolling out DoVi 2…
