My samsung TV's (one from 2018, one from 2022) are used for Youtube 99% of the time. I don't know if I'm just numb to them or something, but I don't directly see ads on them. I'm sure it's phoning home a buncha stuff though.
I suppose I tolerate it if it's in the background, but the moment random stuff pops up on me I'd definitely make sure the TV never connects to a wi-fi.
