Have you ever experimented what you describe all the way to the press?

I have a client who insist on using SWOPv2 for separations, in Photoshop.
But when his jobs come in the door, a custom press profile is used for
proofing instead of SWOPv2 with good success. Isn't it the same as running
this client's separations on an Approval or a FinalProof "if the press is
known to match an Approval or a FinalProof"?

I agree a discrepancy is created, at least conceptually.

Doesn't the color gamut of the monitor also come in the equation? And why
would it be worse for CMYK solids?
