FWIW, the Quest Pro can do both eye and face tracking on avatars right now, although whatever app you're using needs to support it and it's not yet photorealistic. (Meta's been working on photorealistic avatars but my understanding is they're currently too computationally expensive)

I couldn't find a really good demo, but this should give a decent idea: https://www.youtube.com/watch?v=lt0O4_56_qE

Meta also announced plans to use face tracked avatars for video calling in What's App and Messenger, although I'm not sure the status of that.
