Compression also works better on higher-quality video. The compression algorithm doesn't have to try to properly recover the noise.
Also, seconded on the difference a larger sensor and better glass make for a webcam.

Shallow depth of field also means that the video codec only has to concentrate on encoding detail in the [narrow] focal plane. In my experience, the results are stunning (50mm f/1.2L @f/2.0 and diffused LED video lights), and the combination of the well-lit in-focus elements in the image (transmitted by good glass) with the deeply and naturally blurred background would suggest that increasing the number of pixels in the image from ~ 1024x640 to ~ 1920x1080 would probably be far less noticeable than the numbers might suggest.
Another, potentially cheaper way to replace a webcam is to use the main (rear) camera of an old cell phone.
Digital photography, especially using tiny sensors, is computational photography. Webcams are too cheap to have reasonable processing power internally and webcam companies don’t have the budget to create high quality post processing software for the host computer.
