Hello Ingi, all,
we considered such a certification but refrain from starting it for various reasons:
- limited interest by the manufacturer
- communicate the uncertainty budget for the actual measurements (due to
"normal" device variations) - there is no one CIELAB value for a paper.
- unclear requirements for re-certifications (if the recipes are changed)
- a lot of information by some manufacturer (sometimes unstructured, I agree)
regards
Andy

Hello Ingi,
it may be not exactly what you are looking for, but proof.de just released a list of
various paper whites across many availabe papers.
It's german based so I don't know if it's any help to you, but it's worth
a look:

Best regards

Just one small comment on suitable production paper.
It would be nice if paper manufacturers could contribute and send a list of suited paper
for production printing to Fogra 51 and Fogra 52 by doing their own measurement with M1, -
which would make that paper suited for printing according to ISO 12647-2-2013.
I have not done a lot of measurements, but the specs I have found about commercially
available papers either have nothing about white point to D50, - or the measurement is M0
and the suggested profiles for the paper are the old Fogra 39 / Fogra 47 - based on the M0
measurement (even if the paper is almost perfectly correct for printing according to the
current ISO standard according to my own measurements). That again means that the paper is
in fact NOT suited for printing according to Fogra 39 / Fogra 47 because of the OBA that
is ignored when measured with the M0 filter.
There are however no doubt papertypes out there that, when measured with the M1 - and M0
condition are appropriate for printing according to Fogra 39, Fogra 47.
In fact it would be useful if Fogra would start offering paper manufacturers to certify
their production paper as suited for commercial printing according to Fogra 51 / Fogra
52.
It would surely make my life easier if I could look the suitable papers up on the Fogra
website, - and I'm sure for many others as well, - even just color conscious print
customers and designers that would prefer to keep their colors in check cross media.
Best regards and wishing you a nice weekend
