As you can see there is a 6kHz dip (about 3dBr) in EQ'd. So can I correct this by Peaking Filter at 6k with gain = 3dB and Q = 1.09?
There is a 9kHz dip (about 8dBr). Similar correction.

There is a dip in EQ'd at 4.5kHz (about 5dBr). Can I correct this similarly with gain = 5dB and Q = 1.15?

Dip at 8.5kHz (about 5dBr). Similar correction.

But I believe it is more complicated than that. I'm trying to relate Sound Pressure Level dBr on the graphs, with dB in EQ software.

I expect to scale from "dB" to "dBr" you need to know the sensitivity of the headphone and other parameters, then use an equation to calculate dBr?

No, your first instinct is right - dial in an x dB correction in your software to fix an x dB peak/dip.

Be careful to leave some headroom when boosting.

I think oratory purposely don't eq some dip or peak because they are higher than 5 to 6k Hz or oratory listened and think no eq needed there. Some dips are because of sound bounces in the headphone, you can never eq that out. Oratory does not provide group delay like what Amir does. I think you can use narrow band noise to sweep the part you think that need to correct, that will suit your own ear and plus see if it can be eq away.

Hmm I think, for example, my "corrections" at 6k and 9k on the Klipsch HP-3 just make it too bright, so maybe I will just use Oratory default for everything.

Everyone's ear canal is different at higher than 5k Hz, you can use narrow band noise to sweep around high frequency to do your own eq. But some places you can never eq it up or down, that is group delay and where sound bounces in headphone, don't eq that frequency.
