There would be much clearer signs - dramatically higher CPU usage, and tools like yt-dlp running into bizarre undocumented streams that nothing is able to play.

If they were using this compression for storage on the cache layer, it could allow more videos closer to where they serve them, but they decide the. Back to webm or whatever before sending them to the client.
I don't think that's actually what's up, but I don't think it's completely ruled out either.

A new client-facing encoding scheme would break utilization of hardware encoders, which in turn slows down everyone's experience, chews through battery life, etc. They won't serve it that way - there's no support in the field for it.
It looks like they're compressing the data before it gets further processed with the traditional suite of video codecs. They're relying on the traditional codecs to serve, but running some internal first pass to further compress the data they have to store.
