Adobe's 'camera matching profiles' are their version of this. Everyone else (or at least everyone who doesn't license the SDK) has to do this themselves, with a greater or lesser degree of success. What Nikon does very well is to profile their cameras carefully to get exactly the colours they want, and the output of their software matches their in-camera jpegs quite closely. I believe both Adobe and DxO have their own ideas about raw conversion. Nikon licences a software development kit (SDK) that appears to include the core raw conversion stuff, but not many companies seem to be interested. I used to use Nikon View for raw conversions before getting the original Capture NX with my D300. But the quality of Nikon's conversions pre-dates the NX days, going back to Nikon Capture and Nikon View, which I think were written before Nik got involved. More recently, Capture NX-D was built on Silkypix - I don't know if they are still involved with Studio.

Capture NX (& NX 2) was written by Nik Software, authors of the well-known plugin collection, before they were bought out by Google, who then sold on the plugins to DxO.
