The million dollar question here is whether the inverse perceptual mapping

Some things in life you never regain once you loose them. I'll not
list these by item -:).
Of course you will never get the full RGB working space gamut back
from a CMYK image.
Of course you will never get the full film space gamut back when you
convert from an RGB working space back into CIELab.
But we can't stay in CIELab as it's the odorless, tasteless,
shapeless nothing that doesn't display, doesn't print without some
form of device to render to.
You are always better off having digital originals in their full
capture gamut, parametrized to reproduce well to high gamut printing.
But that's not the way the world works. The world is bent on scan for
print workflows, and once the stuff is gamut compressed, the world
scratches its balding pate and wonders how to get back into RGB.
This is not ideal. But it is the way things are. So while the bugs
that plague proofing are a true pest, here for once the fact that
profiles declare the Perceptual intent as default both for Lab ->
CMYK and for CMYK -> Lab makes sense.
Even bugs can be boons, if you look really really hard -:).
