But how about the 24fps?

Did you also enable Settings > Player > Videos > Adjust display refresh rate and set it to Always?

If it is Off then you won't get any refresh rate switching, even with items in your Whitelist.

Eventually the "Adjust display refresh rate" setting will be removed completely once the Whitelist functionality is ready for prime time.

RPi hangs and doesn't return to the GUI at the end of playback, so maybe there's something wrong with Kodi and extremely short duration videos... NUC seems OK though. RPi has this in the log at the end of playback:
