This isn't about a user agent. In basic terms there is supposed to be some kind of software that attests that the browser is actually what it claims to be. On the other side, a server can trust this "attester" or not. So even if you wrote software that always attests what the browser claims to be, Netflix for example could say "nah, I don't trust you bro".
On Android this attestation would be done by the Google play services (afaik). On desktop, the OSs would need to implement this attestation.

Please someone correct me if I'm wrong on this.
