This is 100% my experience and setup. (Though I run Debian for my docker VM)
I did run docker in an LXC but ran into some weird permission issues that shouldn't have existed. Ran it again in VM and no issues with the same setup. Decided to keep it that way.
I do run my plex and jellyfin on an LXC tough. No issues with that so far.
Until they start to force you to connect to "finish" setup. I'm sure it's only a matter of time.
For now my new LG turns on directly to my external device and isn't connected to the Internet. I did have to change a setting to turn on to the last input used instead of the useless home screen.
