I have a 920. It’s awful when compared to my 12 year-old DSLR’s video-out or my 6 (7?) year-old iPhone 6.
Logitech needs to stop using cheap plastic lenses and excessively compressing video. USB3 has sufficient bandwidth.

Also it's just compressing to MJPEG, which is far higher quality than any subsequent h.264 compression your CPU would ever do. The Logitech Brio transmits raw data over USB3 like you're asking, but the resulting image quality is identical -- I've tested them side-by-side.
(Ancient 920's performed on-camera h.264 compression which was later removed -- if you have one of those, be sure to select the MJPEG stream instead.)
