If you're going to that sort of length, maybe just filter DNS requests from the TV to whitelist Netflix and Amazon Prime Video, etc. but block everything else. A custom router might go one step further and only whitelist outbound traffic to IP addresses that were previously resolved through DNS.

Are Netflix, Amazon Prime Video, Youtube etc. IP addresses stable enough to be whitelisted, er, allowlisted without frequent updates?
