for all that having sometimes problems on the shield getting DV triggered correctly, maybe this could be helpfull. i have sometimes problems using DV on other apps, if the netflix or the disney app is started. for ex. netflix app is started but in background, because i used it some hours ago, if itry open a DV movie in disney+, dv will not triggered and the movie starts only in hdr.
so maybe you should close all apps with the nvidia taskmanager before trying or experimenting with DV on kodi.

maybe its usefull, it just only an idea to prevent issues.

I already did that in the past. This doesn't help.
