Hypothetical is beside the point. The hardware is there, the software is closed and you can't verify what is really happening, so the potential threat exists.
Connecting to open wireless networks is exactly the sort of behavior that would be trivial to confirm the presence of, if it were actually present. You wouldn't even need any unusual tools - just set up an open access point and see if the TV connects to it.
