I think its as simple as the blurriness of 24 fps hides props/backdrops/etc better than at higher frame rates. Its the same with resolution. More detail makes the fake things more obvious. An old film shown on a CRT from the 90s vs. an HD remaster on a modern OLED can be almost distracting in how obvious movie props are. This is a big component of the "soap opera effect", where props and scenes become more obvious and feel "less real", despite the higher detail. With time, higher quality sets should balance this back out.
