I don't want or need a "smart TV". I have a Sony from a few years ago that has Netflix and iPlayer and a few other things that I've never wanted to explore. Same as I don't want to use Netflix or YouTube or even Catchup services via my cable box.
I do have a Chromecast and Pi hooked up to my TV. These give my TV smart capabilities, just not built into the TV. Whilst I have them hooked into Home Assistant and the Pi is linked to a Synology which automatically downloads new episodes, the average person isn't really interested in the effort required and is happy enough to be able to use Netflix or YouTube on a Smart tv - after all, why spend £30 on a Chromecast when the facility is already there?
