In what world do you live in where sufficiently advanced encryption is distinguishable from random noise? Not to mention the layers of transport, compression, encryption, and etc that adds applications of 'fuzziness' to the equation. All of this makes finding the id next to impossible vs randomly added data, and that is assuming you had a pure source to compare it to. For my part I can verify you need specific advanced software tools to detect the changes the software we run in production makes and even then it requires a decryption key to decode the identifier id and algorithmic delivery (where the changes are made). This would all just look like compression loss or noise under observation without insider knowledge.
What good would such a fingerprint be if it didn’t survive normal recording conditions?
You're making an untrue assumption based on a misunderstanding of what I've said. I did not say it doesn't survive. I said you cannot distinguish it from random noise without knowing it's there and how to see it, because there is already a massive amount of noise/"fuzzing" in the processing pipeline. In addition partial ids are often enough. Very little of anything processed and interpreted by humans is specifically binary, and short of implementing an insane level of hashing in the bare hardware and verifying all those hashes up the chain, it'll always be that way.
