That wasn't a goal for DKIM. Rather the goal of DKIM was to provide
additional data to recipients, which could be used in a number of ways.
("While the techniques specified by the DKIM working group will not
prevent fraud or spam, they will provide a tool for defense against
them by assisting receiving domains in detecting some spoofing of
known domains." is the charter wording).

DKIM itself cannot alleviate spam, as it's just a tool for
authentication. That means that if the only thing you want to measure
is "How much did DKIM deployment directly alleviate spam" then you're
going to get an answer that's close to zero.
A more interesting question is how domain based authentication helps
domain reputation based systems reduce false positives in spam
filters, or how domain based feedback loops help ISPs and mailers
avoid sending unwanted email. DKIM itself doesn't do either of those,
it's just a platform they're based on.
I don't think we're at a point, yet, where the answer to that will be
particularly enlightening. It may be time to start tracking the data
if you're not already, though.
