I believe it shoots for a basic "flat", as opposed to any 'room curve or preference".
The world of DRC today is huge and growing all the time.
I have zero hands-on experience with any but the very early Pioneer system and modern Audyssey. I have done quite a bit of homework investigating the capabilities on much of what's out there, it can be dizzing and confusing.
I do tip my hat to both Dirac and Audyssey for each offering various levels of complexity (and pricing) making them an excellent choice for either the novice or expert.

@mitchco offers his HLConvolver system of comparing various curves, etc using Acourate, Audiolense and Focus Fidelity software. He even offers personal technical support if you'd be interested in a helping hand dealing with the highest level software.
