Some followup:
I finally gave up trying to get the laptop to match the desktop. FWIW, the laptop has a very wide viewing angle throughout which no perceptible change in color occurs. This is a new Studio 1558 from Dell with an LED backlight. To add more confusion the applet that comes to adjust a variety of display settings shows the display as having a Gamma of 1.0. Moving the gamma setting to 1.8 or 2.2 in the applet emphasizes the midranges and washes out the display.
Attempting to profile the laptop either at gamma 1.0 or gamma 2.2 still shows the display with a gamut having very little more than sRGB. Not really practical for image editing.
After giving up on the laptop I went back to reprofiling the desktop displays at 160cd/m^2 but found them annoying bright. BTW, these displays must have carbon arc searchlights for backlights since only 25 or so out of 100 takes them to the 160cd/m^2 range. So I punted back to 6500/2.2/120 and profiled them both there.
I'm done.
