By endpoint targeting I meant, using the levels eyedroppers to set the black

Am I incorrect in thinking that this kind of Lightness/Luminance mapping detracts from the accuracy of the transformation in an effort to "improve" the final output? Isn't L* fixed? (L*17 in device space = L*17 in PCS - in the AtoB tables)

Everyone keeps talking about comparing the gamut of the source device to the gamut of the destination device. Isn't the gamut compression the responsibility of the BtoA tables and the rendering intent?

I can't decide if you're proposing that the CMM make the choice of rendering intent for the operator - based on the relationship of the source and destination color spaces,

OR

if what you're proposing is really the arena of abstract/edited profiles a la ColorBlind Edit

OR

if this is geared to repurposing.

Also, it seems like gamut compression is less of an issue than gamut expansion (if that's an appropriate expression) in this conversation.
