You made a simple, flat assertion.

Since the context of all email filtering these days is within an
elaborate engine, a purely isolated, literal and simplistic
interpretation of your statement wouldn't make much sense.

I queried about the claim and got back counter data.

Reputation assessment is a complex game, involving many factors.  But
that's not the question at hand.

The question here is whether such assessments are made against
DKIM-validated names.  The answer is yes.
