IIRC the user marketing data exfiltration method pioneered by Samsung several years ago involves a form of Bluetooth P2P/mesh networking whereby a TV with no internet connection can handshake with, for example, a neighbor’s TV which does have internet enabled or, if they’re just as tinfoil as you and disabled their internet, your data and theirs could simply be relayed to another neighbor’s TV on a different floor, etc etc
