The dynamic is just different for those dialling in. People are simply not on the same level than those on site who have a clear advantage. I saw this working relatively well when the person remote is some senior person coming with a lot of experience to insert himself in the conversation. It's maybe even better because others may now have the chance to say something (lol) Generally speaking, this works well, when the main persons of the meeting are not all on site so that the videoconference becomes the primary communication. Otherwise, it's just that those who don't say that much will say even less (or nothing).

Btw, I'm also a big fan of remote working, but no matter how good your communication skills are, you're left behind on the longer term within an hybrid team. You just can't build all these relationships with smalltalk etc. that's another problem

I guess it also depends on the company and the style of the employees you work with - in my old organisation we made it work because it was embedded, but also everyone was just genuinely nice and not trying to score little political points here and there.

Even with over 500 employees, the lack of a career ladder as such meant there's little to gain by being the loudest in the room or trying to work the room. Perhaps that's also an ingredient - it might be easier to minimise others' egos when you're also in the room?

People in a room communicate via gestures and body language. Leveling that is tough.

That's also one reason why many people on autistic spectrum prefer video conferences over physical meeting - responses have to be given more explicit.
