No vendor will use SMB to check for connectivity. They would check for relevant internet paths. Though I doubt the companies would be ballsy enough to connect to unsecured networks, if that breaches laws in a country that the tv is sold it may have legal ramifications for the company. Edit: then again my argument is based on logic and risk, not two factors marketing and sales teams consider very often..
