Why can’t you buy a good webcam?

exactly, audio is the most important. Nobody needs to see your unshaven sleepy quarantine face in 4K. But if they can't hear you, or there is a lot of noise, the meeting is ruined

Actually, nobody will ever see your face in 4k because none of the platforms that are used for this will ever transmit video at that resolution. Most cap at 1080p with a very heavy compression.

Also understand that real time compression is different from offline compression. To compress well it requires a huge amount of CPU. Real time compression results in higher bandwidth for the same image quality but more typically less quality for the same bandwidth.

Never say never, I'm sure it won't be long before 4k's as commonplace as 1080p (with heavy compression).
