It doesn't matter whether you run android TV from the TV itself or an external device.
All the popular streaming services throttle or block open devices.
There's no regulation on it, because regulators want locked-down hardware that can only take actions approved by them.
Even with that, there are plenty of safer distros, or you can even get a cheap mini pc and throw one of the many awesome Linux distros on that have zero tracking and are far more capable/performant.

This just isn't true. Have never encountered this.
More recently I've tried hbo max and it does the same thing. Could not get higher than 720p, even with chrome and whatever DRM options theoretically fix the problem.
I remember that being a problem in the past, that you were limited to lower resolutions.

Your only options are to sail the high seas or use Android TV.
If you want a high quality TV for the best price your best bet is either disable/opt out of all the tracking data, or even better just never hook it up to the internet at all and plug an AppleTV or Chromecast on it.
If you look for a Samsung TV without “smart” features you pretty much have to find them under “commercial displays” and you’ll pay a premium for it.
