[argyllcms] Gamut mapping didn't help with shadow detail in monitor profile

I was wondering if anyone could provide some tips to coax out more shadow
detail using Argyll. I'm finding that compared to Color Eyes Display Pro
(using an Eye One Pro), I'm missing a bit of shadow detail. I've tried
building profiles using both the Eye One Pro and the i1Display Pro but the
shadow detail I'm used to just isn't there. The settings for white point
and gamma were derived by measuring an NEC 2690 which was calibrated and
profiled with Spectraview II. If I measure the white point using an Eye One
Pro and set the black point target to 0.30 cd/m^2 in Color Eyes Display Pro
(gamma set to 2.2) the HP is pretty well matched to the NEC in terms of the
TRC but it's just completely different using Argyll. I've tried raising the
black point target in Argyll but there was no improvement. I've also tried
gamut mapping as indicated in the link below but it made no difference at
all.
