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:
