"even the best deinterlacers" ever can't+won't overcome the fundamental high spatial frequency / temporal confusion inherent in an interlaced signal.

Lots of movement and/or lots of fine detail isn't a fundamental problem - the fundamental unrecoverable problem is the specific combination of fine detail and specific movement, as you illustrated.

Where there's movement + fine detail that is recoverable, it's often argued that it doesn't matter so much if the display can't recover it because we're less sensitive to detail when the image is moving. It's not true for eye-tracked motion however - but then most modern displays are already a disaster for eye-tracked motion anyway, so it matters less.

Cheers,
David.
