It IS true that the film projector shutter cuts the light off and leaves us
in the dark for (roughly) half the time. Not just somehow different, but
fundamentally different.

It's less than half, quite a bit less in projectors with narrow blades. And
the "darkness" created by the shutter blade sectors only interrupts the
projected image. It doesn't create a lingering piling on effect in the eye. This
is why POV is not true, and why flicker in film projection is not the result
of the darkness. In fact, if you replaced the dark sectors with, say, white
light, you'd still have flicker, because it's caused by the intermittent
images, not the dark intervals. It'd be a weird flicker, but it would still be
flicker.
TV doesn't have the clean off/on dark intervals, does it? There's always
some kind of scanned image on the screen, from what I've read. So yeah, it's
fundamentally different.
