gamut "correction" of ICC profile

i now have two different ICC profiles for the same paper. the "white" one made through efi XF and the "colored" one built on top of the efi LIN with profilemaker.

as you can see the gamut is wider above L50 through profilemaker. but it lacks the shadows.

no i would like to have those two profiles in one i guess...

the efi profile was made with a IT87.3 chart the efi way. they first make a device link for the RGB channels and then print the IT chart using CMYK+RGB

profilemaker just prints a 2400 patches chart using all 7 inks.

the patches from profilemaker in general look pretty dark. and when scanning them everything is darker then the reference.

which conlusions should i take from that?.. lowering the ink limit in the chart? from 700 to 400?
although non of the patches actually has too much ink as the LIN settles that!..

any advice is highly recommended as this is my first 7 channel profile.. thanx
