Doesn’t show on TV or soundbar? I’m not sure what brand TV you have but guessing since the TV isn not doing the processing and passing it along to the end device soundbar it does not show.
Atmos and trueHD are not the same. TrueHD is more like your standard surrounds with 8 channels, and what Atmos has if I recall are sounds objects that can be processed different speakers dynamically in a 360 sorta layout so you have have things like ceiling speakers. Afaik Atmos has a trueHD fallback ,sorta like DTS-MA has a DTS core. (I’m sure there are websites that can explain it much better than I ever could)
If you only have a soundbar not sure how much difference Atmos would make over TrueHD.
