It does not do the desmosaic. But what it does in the DNG conversion process is to add metadata about the white balance and the color matrix that the demosaic process will use, values usually hardcoded into converters for proprietary raw formats like CR2 (and specific per model). *hint* it is likely the same values that Adobe use for the raw processing. That's where I would dig to see what are the differences.
