At cruise RPM that effect would be completely lost. There's not a
bird or human alive that can discern stroboscopic effects of more than
a couple hundred cycles let alone over a 1000. Most of us can't even
discern 60 cps.
Birds have much better vision than human beings, and I don't believe
anyone
has tested their ability to discern stroboscopic effects. And the front
fan
on a turbofan is turning at around 40-50 revolutions per second, not
thousands.
Guess again.
