You were able to block everything in the past but no longer. Samsung catched on and now serves some ads over the same domains they distribute their firmware updates, install apps, get the program guide, and check the online status.
If you block those domains the Samsung TV loses most of its internet features and also seems to go crazy and requests all domains multiple times per second, defeating deep sleep of the TV.
Hard but doable. So far everything hardcoded of that sort has been successfully extracted (or leaked). I don't think they'll be adding expensive TPM chips.
