Since there will also be a unique "sourceId" for uniquely identifying the source, then my point is that the "label" wouldn't really add anything (unless it's needed for something in Peer Connection which I'm not aware of...)

Choosing not to report brand information is one thing, providing an
application enough information to allow them to inform the user in a
meaningful way is another.

When we were building some of this stuff, the many devices I have
would sometimes lead to situations where I wasn't sure if the app was
busted or if it had chosen the wrong device.  Displaying a "label" was
what ultimately fixed the issue - check label, go to identified
device, test.

That doesn't mean that the labels can't be made unambiguous and less
useful to an application for fingerprint, but I question the value.
At the point that the application can take a photo of your face, what
sort of leak are you looking to avoid exactly?
