Here is my philosophy...
I do have a pretty decent 2.1 system (which costs more than those cheap Atmos soundbars) in the form of a stereo soundbar and a subwoofer (obviously). I honestly don't mind where the sound is coming from. It irritates me anyway since the picture is also in front of me. It is like with Dolby Surround in the beginning. They put in all kinds of effects but it got less and less over time. What I do care about is a good dynamic range with decent low frequency representation. I am therefore perfectly fine with good old Dolby/DTS 5.1 for which the LFE channel is preserved. Easy setup and works always... at least by now. It took Sony years to stabilize the standard multi-channel audio formats on their Android TV sets...
As for "HD" audio, it is pure marketing BS. 16-bit 48kHz is perfectly enough for transportation to the end user. Only for production/post-production is it helpful to have some more bits. Good thing about "HD" audio is that those formats either have backwards compatible cores or can be transcoded/downmixed to some lossy Dolby/DTS compatible format.
