Genelec's GLM and Neumann's MA-1 EQ correct above the room's Schroeder freq. to a limited extent. Does that mean they "tell you lies"?
I don't know what GLM and MA-1 use to calculate their corrections for different parts of the frequency range, but what we can assume is that those two programs have the benefits of knowing the "subject" in and out. They know exactly how the direct response looks like for the particular speaker model, and can therefore use both the measured room response and the known direct response when calculating what corrections are needed for the different parts of the frequency range.
Dirac on the other hand has no such knowledge of what the particular speaker's direct response looks like, for them, it's just an unknown "subject" and the only thing they can know when it comes to the frequency response of the unknown subject, is what the microphone has picked up at a bunch of non-reflection-free spots around the main listening area.
