It’s funny how many come over and ask if I have a “smart tv”. Or when they are shopping for a tv and want a smart tv. I wouldn’t ever give up my appletv’s. I love the interface and I have sideloaded some apps. I can’t live without airplay either.
Seems like most normal people are ok with the crappy tv’s apps because they kinda work People don’t seem to care how things look or work I guess.
(This isn't necessarily a reply to you but to add on in agreement...)
Smart TV's were created for people who don't know better and have the most basic of streaming needs. The UI is incredibly slow and most of the apps are limited, depending on what brand you get and what OS it runs. There is zero chance you'll get me to install an Android TV in my home. (Bandersnatch doesn't work on Chromecast either, BTW.) Vizio was forced to stop collecting & selling data from their Smart TVs.
Though, I stayed at a long term AirBNB for work last year and they had a Roku TV, which I really liked, because, well, it runs on Roku. It surely wasn't the most technologically advanced TV but it was fine for what it was. I would consider it as a 2nd TV for sure. Sadly, I don't think there are any high quality "dumb" TV's. Though, if anyone has one to recommend, let me know.
The fact is, Apple got into the streaming game way too late. Instead of leading the way, they are playing a bit of catch-up and many people have settled into their ways. I love mine though. You'd have to pry it away from my cold dead hands. I wish they made a portable one to travel with.
