if one forced "Best Match" setting on Kodi to use higher sampling rate than 48kHz on 5.1+ audio tracks, it would probably work fine on all occasions on my end

This part would probably require Kodi source modifications, not that scared of that yet, altho I've never done APK building for Kodi before. I've modified and done custom Kodi builds for windows in past so have to learn new things while tackling this =) I'm just first trying to figure out what works and what could be done about it without too big negative side effects, right now it feels like just brute forcing that Best Match mode to run high enough sampling rate to bypass DD+ would do the trick.
