Seriously, why don't you even try to calibrate the Standard mode?
It's the most precise and correct picture mode on these displays.
You don't really need RGB Gain controls. Both your VGA LUT or your CMS
engine can take care of the white point (with the appropriate settings
for either or both the calibration and/or rendering). But if you wish
to set the WP with hardware controls then you can do so from the
Service Menu (I preferred this solution myself when I had an U2410: WP
from the SM, LUT calibration to native WP target, gamma closest to the
native response, matrix+gamma profile, absolute colorimetric rendering
intent).
If you calibrate the Standard mode, a basic gamma + matrix profile
will be sufficient to achieve dE2000<1 and this profile will be
compatible with every CMS engines (it will also help to avoid the
possible problems with the blac point compensation).
The Custom mode has problems with the color mixture (it's not
additive, no matter how you set it up with the triaxial
primaries+secondaries controls).
A cLUT profile may correct these anomalies but what's the point if you
have a Standard mode without anomalies?
Also, the contrast ratio was the highest in Standard mode, as well as
the relative precision (banding-free gray gradient, even after the
corrections).
