It's not in about:config by default, you have to create it. Creating it still works. It has never appeared there by default (also not in 80 or before), afaict - it's not in all.js or firefox.js in the results on https://searchfox.org/mozilla-esr78/search?q=ui.prefersReducedMotion (which is the 78 codebase) despite the pref being in use.
