Easy do-it-yourself with Wireshark to see if that TV is
watching you and your files.

Just make sure that the machine running Wireshark (or equivalent) is
attached to the same network switch as your TV and your NIC can run in
promiscuous mode, or you'll never see the traffic.

Actually, if you are using a switch, you will not see much (if any) of
such transactions. That is the purpose of a switch - to forward packets
out only ports where they need to go. Thus, the switch will take the
packets between the TV and "outside" and forward them back and forth
between those two ports, leaving your third port in the quiet.

A "hub" would show you a lot more.

Hubs are hard to find. (coincidence ?)
Switches filter IPs, not Ports. Firewalls filter ports.
Anyway, if you set up a wireless bridge and monitor that in
promiscuous mode, you would pick up all the traffic. Or put a linux
dist as a NAT server between the TV cable and the plug, and run
wireshark on that.

TV ----> Linux NAT Server (wireshark) ----> Cable or antenna

True.

What I said was essentially (or more precisely, completely) wrong.

Or a switch with a "mirror" port set up on it..

The switch may or may not forward unicast traffic to a MAC
address that's not been learned. Switches are frequently
learning bridges. Some are not. You may need a hub,
not a switch to do this.
