That's not my experience at all. Crystal-clear and virtually zero sensor noise in regular light conditions. Maybe you got a bad one...?
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.)
