None of those things have anything to do with the TV being "smart" though, it's all up to the crappiness of modern HDMI.

Removing app support from the TV would not fix it. Actually, it sounds like using the smart features of your TV to watch video instead of an Apple TV would actually reduce the bugginess?

I have a 10 year old non-smart TV. It predates HDR, but just basic ARC and CEC still regularly trips it up. To the point my 5 year old knows how to re-select the sound bar output to fix when the audio breaks.

Ah, but most of the slowdown from this messiness is due to all these mode changes being handled at the application layer in sandboxed userland daemons on a non-real-time OS. Before smart TVs with application processors “fast enough” to (barely, slowly) do these things, the “control-plane logic” for a TV’s DSPs was handled effectively instantly by purpose-designed ASICs.
