We put a Samsung smart TV in $wife's studio for her upcoming cooking class show; denied all permissions for its "smart" features (the terms and conditions are worse than those of Disney's Walk Around The World brick sponsorship) but it still did .75MB of traffic in <12 hours

Also, every 20 minutes or so it prompts us with a banner to activate the smart feature so they can harvest all our viewing data and sell it to all taker. Like Akhmatova said of Petrograd, @Samsung wants our TV to be "...a drunken harlot who didn’t know who was taking her…"

The "Unknown" traffic on our TU7000 is of keen interest.
