Something that gives me confidence here is that in macOS Sonoma Apple have gone all-in on sharing screen content on a webcam feed. I feel this will motivate Zoom and Teams to take this into account when compressing video. But don't forget, if high fidelity is super important, you can always switch to a normal screen share. I just find that a lot of the time, this isn't the case, and it hurts the communication overall. But yeah, I do encourage nice big, short, bold bullets in an attempt to minimise this risk.
