Can you post the command lines and outputs of iccgamut and viewgam?
Do you interpret the numbers correctly?
Example:
$ viewgam -i sRGB.gam printer.gam out.wrl
Intersecting volume = 512354.4 cubic units
'sRGB.gam' volume = 833600.9 cubic units, intersect = 61.46%
'printer.gam' volume = 552445.5 cubic units, intersect = 92.74%
$ viewgam -i AdobeRGB1998.gam printer.gam out.wrl
Intersecting volume = 552205.4 cubic units
'AdobeRGB1998.gam' volume = 1209985.9 cubic units, intersect = 45.64%
'printer.gam' volume = 552445.5 cubic units, intersect = 99.96%
This means that
* the printer can reproduce 61.46% of the sRGB gamut
* the printer can reproduce 45.64% of the Adobe RGB gamut
* sRGB can reproduce 92.74% of the printer's gamut
* Adobe RGB can reproduce 99.96% of the printer's gamut
