Our enterprise deploys dumb monitors with no SMART OS and no WiFi, then connect an enterprise walkup PC to the TV, managed by corporate IT.
I factory reset all my personal SMART TVs, manually set them up using the remote, and did not connect them to the internet.
All SMART TVs use Automatic Content Recognition (ACR) which takes fingerprints what is displayed on the TV (not just the SMART apps), sends all your data back to their far east servers to sell to advertisers. Depending on what information is sent, it may be considered an export violation under US EAR and ITAR regulations. Australia has similar regulations. Since the telemetry is likely encrypted, you will never be able to confirm what is actually transmitted.
