Yeah I really hate that I can no longer easily hook up my laptop to my LG OLED tv and just press play on the movie I downloaded. Nowadays I have to download PotPlayer, change the renderer and increase the brightness whenever I want to playback a 10bit HDR movie.
IMHO the best solution for you would be to just fire up Plex/Emby/etc on your laptop when needed and use the Plex/etc app on your TV/streaming box and play over the network. Wired is more reliable of course but wifi works fine most of the time too.
You can play back HDR and Dolby Vision 4K content just fine with Plex and it is all decoded on the TV (or streaming box) so no need to mess around with Windows video settings to get HDR looking not-shit.
