Have you used your System Prefs Sound to:
- show volume in menu bar using the checkbox option??? That sure makes access to set the volume quick and easy. May also help save blowing out some speakers at some point as well.

Yes, I have the volume setting in the Menu Bar.
- set the volume level you want for when your Apple TV is selected. The Volume in menubar allows that as well for both output source and volume level.
That is the way I adjust the volume now.
I would expect the preference for the Apple TV to stick and remain in between uses, but maybe not.
That's the reason for this thread, the volume does NOT stick.
And just one other thought, and I'm not sure if would work or not, but maybe have a look at using
Audio MIDI Setup app but I don't know if it works with the Apple TV or not. If it does, it should be able to be set to a preset volume level, but maybe too involved to get it enabled each time you want to use it.
Tried changing many MIDI settings. No help.
I would think just using the Volume icon (menubar) would be easiest and safest, and gee, maybe two or three clicks shouldn't be too much of any extra time or effort.
Yeah, it's not hard to change the volume, but I don't want to have to do it EVERY time! I also noticed that the same volume setting comes up for other AirPlay devices (ATVs), always about ⅓ volume. It must be some default Apple has set up for Airplay/ATV. If I Airplay directly to my Denon AVR, the volume setting will remain where it was set last time.
