I'd argue a video call is worse for facial nuances. The nature of having both camera and screen is the person you're teleconferencing is never actually looking at you.

Modern VR headsets already have eye tracking, it's not too out of the picture to imagine some rudimentary face tracking to capture the rest of the foundations of expression. In my experience the sense of "thereness" is much greater in a VR room than a teleconferencing session; but it's difficult to compare since VR presupposes better audio conditions.
