@cesar92 see above, I forgot to tag you in my reply.

@ashlar Thanks a lot. 
I will try to copy part of your configuration to see if it fixes TV HDR switching off on video stop issue with madvr and nvidia rtx30xx card (i have windows 10 21h2 LTSC to begin with) 
I wonder if madvr HDR tonemapping mode will trigger LG Oled TV HDR mode.

Tone map mode still activates HDR mode as long as you have that HDR mode thing checked off under it.  This did nothing on my 3090 to help it return to normal after an HDR video though.  as long as If i use anything newer than madvrhdrtonemap113 I either don't get HDR mode to activate or it opens up in some weird window and doesn't work.  If I use a very old driver it will return but then I can't play any games on that PC, heh. Right now i just have an AutoHotKey script set up so it restarts Kodi with CTRL+K after it returns from HDR.
