I finally got tired of the nags and gave in to the update, and I'm not hearing any difference in terms of audio. I don't like what others have already complained about, though, namely: having to navigate and click on "Info" to confirm whether a track is Atmos. I also don't understand why Apple wouldn't want to display that Atmos badge on-screen, given how much hype and money they've sunk into it. Plus, there's so much empty real estate on the Apple TV display screen to begin with; why not fill it with some useful information? (And some bigger artwork!) I don't get it.
