Perhaps we've overestimated the need-gap[1] for good quality webcams? Most people seem to be just fine with mediocre webcams for that video call in which their video is anyways going to be compressed and resized to small window if there are multiple participants.
That doesn't mean I didn't waste my time in trying to build a better webcam like others here, I tried to convert a old point-and-shoot into a webcam using CHDK firmware but I couldn't find a way to get the video stream.

I was underwhelmed with the Brio but I eventually got used to it. It’s not the upgrade to the 920s I had imagined it to be but it’s good enough to keep.
And yes, I used Logitune to tune as much as I could. It was horrendous out of box.

I'm using it on my home computer and my work laptop, but don't want to install the software on the work laptop. So I must live with the extremely wide FOV there.

I ended up getting Logitech Brio. It's expensive for a webcam, and honestly I'm a bit peeved - I don't feel I am getting my money's worth in terms of image quality. The software is also absolutely atrocious, so I don't really use it. But it is the best compromise of image quality and FOV that I could find.
(if your question was about DOF / bokeh/ blur, no webcam will do that and so far I haven't liked any software options. I just put a black collapsible photography background behind me so nothing but me is in the photo to begin with :)
