Gracol has a substrate whiteness calculator to compensate for
differences in paper whiteness, which has some degree of success with
papers with OBAs. It's available on the Idealliance website. You may
find it useful.

> “It’s the white stupid” has been my most recent mantra. I’m a retoucher with a new client who’s printing ranges from “natural” white papers to papers containing high amounts of OBA’s. So, in attempts to please this client I have decided to fall into the OBA rabbit hole without any detail understanding as to how printers use the icc standards workflow ( i.e. GraCol) when printing to these papers. As I understand it and putting it simply, the GraCol control strip can only pass certification when printed properly on paper containing no OBAs and only a specified amount of brightness (i.e. L=95). So this leads me to two main issues. One is how to proof my work for this client and simulate how it would look on a bright white paper stock (e.g. McCoy Silk)? Well aware that the white of the paper (blueness) influences the overall color well into the midtones. And two, can a printer make use of the "non-standard" proof and file that created it? Any help on this matter is appreciated.
