This is just a PSA to warn people that this can fail: I just tried this in my lunch break. I have LOS 17.1 on surnia (old, I know). These settings completely disabled my on-screen home button and other UI elements, and setting the anim scale back to 1.0 and rebooting did not fix that, no more home button for now. I probably have to reset the phone, did not find any further info so far on how to fix it (pointers, anyone?). But the UI seemed snappy indeed at 0.5 ... Edit: "other UI elements" including e.g. the Tab switcher in the Lightning browser. The widgets are all displayed, but totally unresponsive.
