To be fair, the difference between SDR content and 'base' HDR10 content is so massive that it makes me wonder if DV or HDR10+ is actually worth caring about at all.
The reason I started this thread is because I recently bought a £3K Sony 77" Bravia OLED TV and wanted to know if I am missing out on 'experience'.
Ive been a long time happy user of LE/Kodi on a Pi4 8GB. The audio/video support is second to NONE. The buffering/cache options are great for smoothing out the experience for non local content and it just works.
I started my journey with LE, with a USB HDD connected to the Pi4. I then changed to an FTP/S backend with a server (in a datacenter), but still with local library. Today I run a Jellyfin server on 13th Gen intel hardware with a massive drive array etc... in a datacenter and use the Jellyfin Kodi plugin to sync the libraries.
LE on a Pi4 in my experience DESTROYS everything else I have tried, including the Nvidia Shield TV Pro (which people rave on about)... Yes it does DV, but the hardware is dated, its underpowered and doesn't have enough RAM for high bitrate content.
I am awaiting delivery of a Pi 5 8GB which I plan to make my main media center system and retire the Pi4 to the bedroom.
In short.... There doesn't appear to be one single perfect device out there which supports everything.... But the best around in my opinion is certainly LibreElec on the Pi 4 (and hopefully 5).
No Dolby Vision or HDR10+? Meh.... I don't think im missing out on much at this point.
