Neat, more open competitive standards is nice, but it doesn’t matter how much your phone/tv “supports” spatial audio, it’s not going to sound any different from stereo coming out of the built-in speakers.

Imo, the qualify differences are only really noticeable across these speaker setups:

1. Built-in speakers $0 (mono/stereo, anything above is indistinguishable)
2. Soundbar $200-$500 (mono/stereo)
3. Basic soundbar with auxiliary surround sound speakers + subwoofer $500-$2000k (surround sound starts to matter) 3.5. Maybe speaker towers?? I have very little experience with those.
4. Actual surround sound with near-professionally installed/positioned/calibrated speakers in a properly shaped room $3000k+ (Dolby/DTS:X starts to matter)

In my experience, no audio track is going to break those barriers and ceiling reflected noise is basically placebo. You can fudge it decently well with headphones and fancy spatial audio tracks, but even that isn’t quite the same.

I’m no audiophile, though, so your mileage may vary.
