Smart TVs take snapshots of what you watch multiple times...

Not if you never connect your smart TV to the internet to complete the setup and instead use it as a dumb display (I hope)
Certain brands automatically connect themselves to open wifis I think so there is that to consider as well.
I remember hearing that some may even have LTE to fallback to.
Damn, I can rule out open hotspots, but wouldn’t know where to start checking for LTE (a Faraday cage comes to mind…)
