What they said in that post was that no preset EQ profiles exist, i.e. you create your own profile/presets.
I agree with their stance, how would they know better than you what the EQ should be, especially in light of the different variables in play, they note: different positioning on your head, ear size and shape etc... I would add a few more variables like the voicing of any custom cabling, and the effect different source gear has.
They can't possibly account for all of that, so they let you create the EQ profile (your post suggests this is only an SPL correction app, which is incorrect).
