The way frame rate work on conventional film vs. an LCD are completely different. It’s like trying to ask the bitrate of a Vinyl record.
Conventional film projectors don’t show each frame continuously, they transition the shutter blade smoothly between frames, and projectors often flash each one a couple of times (48 or 72hz). A cinema projector is going to demolish a LCD in smoothness and motion quality even if it technically has a higher refresh rate on paper.
