24fps movies on 12 series vs 120Hz 13 series

Does watching movies on a 120Hz screen have smoother fps compared to a 60Hz 12 pro max as it has to do a 3:1 pull down or does Apple do such a great job there is no difference in judder etc?

@james do you have insight on this subject?

In theory, 24fps content will set the screen to 24Hz while playing…so yes, it should be smoother.
