No, that's not how it's worked in any game that's done this before. [Edit: at least that I can think of]
Retail or direct to digital, you get the same game with the same online content.
I imagine the "extra content" might just include the skin viewer, terrain editor, maybe some behind the scenes stuff, the hi-res pack as default, maybe including the full skins library, or something similar.
P.S. The $30 also includes 2 months sub, so that's what the money really pays for.
