In post production we strive for equal wide bandwidth  to allow for precision keying in composites. This is why high end visual FX houses use 4:4:4 in Ursa and Flame/Inferno .
Film work is even more demanding in quality and any datacine/telecine/scanner must offer a wide band response to faithfully capture all the data we need for VFX along with other increased technical demands.
Equating this to the eye's perception is misleading as that has nothing to do with the image manipulation we need to do to the images prior to any transmission.
