This about right for Epson dye inks. The paper choice will also determine
the amount of colour change. Epson paper (gloss) exhibits around this change
in yellow so I can assume it would be more the inks but somewhat the paper.

Now please don't think of this as silly but, profile at a decent dry down
for a customer proof for a quick client proof, and profile for the type of
delay before the proof will be delivered to the pressmen.

It's the ink that makes it a moving target. Red on Epson dye ink is
incredible. When the paper comes out of the printer the reds are so rich,
way more gamut than press , but while holding it in your hands the yellow
disappears leaving a dull bluish red.
