Sonos Arc, Apple TV 4K and Dolby Atmos/Vision Setup

I have a 4K Apple TV and a Sonos Arc. Is it possible to output Dolby Atmos and Dolby Vision? I don’t have either of those options visible in my Apple TV settings when I’m told that I should. My LG tv has only HDMI ARC and not eARC. Is that the issue?

Not having eARC is an issue here, as Apple TV 4K outputs Dolby Atmos in high bandwidth Dolby MAT format, which isn’t supported over ARC connections. Play audio in Dolby Atmos or surround sound on your Apple TV - Apple Support

As Sonos device are designed to connect directly to a TV set, there really isn’t an alternative with your current setup (unless Apple TV is used for all input signals).
