Thanks again for putting me in the right direction. It's very helpfully.
I run the iccgamut without any other option than -v.

I have updated the wrl file now. Anyway profcheck is very interesting.
This is against the eye-one match made profile.
profcheck easyrgb12-argyll.ti3 easyrgb12.icc
Profile check complete, errors: max. = 12.543195, avg. = 6.023216, RMS
= 7.052291
and against the profile made with argyll
profcheck easyrgb12-argyll.ti3 easyrgb12-argyll.icc
Profile check complete, errors: max. = 5.446567, avg. = 1.637336, RMS = 2.100115
Since my English is limited I have uploaded the files here:
