It's easy to imagine a time when the TV includes it's own 5G modem or that Samsung would make a deal with Amazon or Comcast for access to their wifi mesh networks so the TV can get online without user intervention.

I highly doubt that. Rolling out this network is a lot of work and I'm nearly 100% certain this is to reduce claims of non-working devices caused by bad WiFi, plus maybe the option to sell network access on a wide range of devices.
Avoiding blocked network for TVs and other "smart" appliances is surely a nice benefit, but I doubt even 1% of people actually block network access (hell, most probably want it!). There's no way Amazon would pour that amount of effort into extracting that minuscule piece of tracking data.
I only know about LGs but they have a service remote that you can use to change the region. Maybe Samsung has a similar thing?
