I know something about skinning but nothing about Kodi core, so I’m afraid I can’t answer your question. Only thing I can think of is that maybe you added the first bunch of movies with an older Kodi version and the last ones with a more recent Kodi version, and something has changed in Kodi core between those versions… But as I said before, only guessing…

I found out that this magic happens when I turn on my AV-receiver LOL. I do not even want to know how or what is done there...

But back to the matter a last time 
Fact is : I moved back to put only the real codecs into my .NFOs because this is the "right" way in my eyes, so TrueHD stays TrueHD etc., like you say yourself
Atmos and DTS-X are way more for audio streams like HDR is for video.

Would you consider staying with your implementation of codecs and putting out an Atmos or DTS-X logo like you do with HDR?

It would be also grouped with these logos : 4K, HDR, Atmos, DTS-X etc. That is far more appropriate. You could take it out of the filename, too. Yes I know that that there are (I have it, too) audio streams then which are not Atmos or DTS-X enabled. But it is more like a general "feature" of the movie then. I saw an alike solution exactly out of this problematic elsewhere, but I like your skin way more honestly.
