Is it so hard to have just one portion of wall with a neutral color in one's home office setup?

I work in different part of my home, but I dedicate one small space for video calls, where I stand, not sit. It is designed to provide a plain background. If I didn't have a wall at my disposal I would have installed a white ikea roller window blind on the ceiling. It is much more effective than any blurring/background replacement algorithm.

You choose to work from home, you choose to welcome work in your home. The good thing is you still have the liberty to limit and design the small part of the home you are welcoming your coworker's in.
