We should all have the problem of fearing that we've been coasting on our ridiculous good looks. :) But seriously, as I think you meant your comments...
Videoconferencing seems to encumber both communication and charisma in some ways -- big and small, apparent and subtle.
For example, it seems like even slight latency or difficulty hearing people can make a very smooth interaction seem non-smooth.
And (as was exceedingly painful to me in a recent team meeting), none of the tools currently available would've come close to having a real-world whiteboard. There have been CSCW research efforts at this for a few decades, but, in practice, at the moment, it's usually just a dumb camera&mic, and sometimes screen-sharing.
Maybe, in getting an impression of a person, people haven't yet re-calibrated expectations for the videoconferencing media we're currently stuck with?
And maybe there's still some charisma projection adjustments that individual people can try tweaking, if they want, such with lighting, eye contact, lens distortion, etc.? (As someone who once dabbled in studio portraiture, I'm aware of some ways I could look better on videoconf, but it's been a relatively low priority, compared to countless other aspects of startup tech work.)
