[argyllcms] Colprof question

Hello everybody,
Could anyone please help me understand why I¹m not able to get smooth curves
from colprof?
What I mean is that if I look at the curves inside the ISOcoated standard
profile with xicclu I see something like image1 and with colprof, starting
from the same CGATS values and using differrent options combination, I
always end up with something similar to image2...

Thanks
