Peter, although cine film was shot at low frame rates there's a multiblade shutter in the projector that flashes each frame on the screen 2 or 3 times. So although motion will be (even more) badly aliased the large area flicker will be greatly improved.
A refresh rate (to use modern terminology) of 16fps would be really horrible. Baird used 12.5fps in his 30 line work but that was with a very tny screen. Coming back to modern times, LCD displays have zero order hold, so there's no large area flicker regardless of refresh rate.
