To my understanding, if you select the AirPlay Icon from the now playing screen and then control nearby devices instead of selecting the Apple TV via the AirPlay menu, then you can play music from the Apple TV directly. This works for me as well. It will also indicate this by showing Apple TV under the play button instead of iPhone -> Apple TV.
the only issue that i have with this solution, is that the music randomly pauses and I have to press play all the time.
What you describe is available when various devices in the home are already playing stuff... It's a useful remote control function.
But in this case, the OP/Author wants [wanted] to use his iPhone, presumably with an excellent UI, to browse, select & control what gets played by the ATV4K that's plugged into his AVR. I'm pretty sure that's Google's operational model for the ChromeCast devices.
With my iPhone, I can fire up Pandora and establish a ChromeCast connection with my soundbar, and I'm pretty sure the chromecast device [soundbar] maintains an authenticated connection with Pandora, playing what the iPhone app tells it to. I know Netflix worked this way on ChromeCast, controlled by a Netflix app running on a cheap Android device (or an iPhone), over 10 years ago.
To be honest, the Apple Music / iPhone / HomePod relationship may have obfuscated elements of this - seems I've started Music playing something independently on the HomePods, then found the Music app on iPhone providing some remote-like function?
