I just used Zoom for the first time, this morning. I had a ferret around, but although I can see an option in meeting (advanced) settings to enable it, I saw nothing else anywhere to actually make use of it. This is using their system through a web browser (Firefox).
Supplemental: I just downloaded their desktop application (RPM file on CentOS, so Fedora's probably more advanced). In there there's a virtual background configuration option, and the background colour is selectable (you click on the background in the preview from your webcam video).
Currently, I'm in a room with pale yellow/cream walls and it's sort of working, mistaking some skin tone. If I was in a room with different coloured walls it'd work better. I do have green walls in a room with a Fedora installation, so I'll try that out shortly.
So, a green "screen" isn't required. But you really want a flat coloured wall behind you. I work in video production, and for those unfamiliar with chromakeying, or colour separation overlay (CSO), bold primary or secondary colours are best (red, green, blue, yellow, cyan, magenta), and you're better using colours opposite to skin tone (green, blue, cyan being the most opposite).
Thank you all again for your answers. I have meanwhile found something that gives me some hope: Using OBS Studio as a virtual camera on Zoom with obs-StreamFX plugin on:

Now, my difficulty is how to install obs-StreamFX.
