The spectra curve on this paper looks pretty straight without any bumps in the spectra curve.

So I guess the paper is without any optical brighteners.

The technical way to confirm this is to compare the white
spectrum with and without UV. Some instruments allow this,
such as the Spectrolino and XRite DTP70 (where you can put
the filter on and off), and the i1iSis can take
readings with and without UV illumination.

So I should make the profile without -f

Probably safer to, if you are sure that the paper doesn't
have any whiteners.
