DxO makes DxO Optics and DxO Optics Pro. They aren't theory, they are actual raw converters, not so unlike ACR/LR.

Does DxO guarantee that DxO Optics Pro can deliver the full DxOMark sensor DR to an image file?  Of course not: for one thing DxOMark DR is only based on grey, not colors.

DxO profiles the lenses with each camera and creates profiles for the lenses and the cameras. If anything, I think DxO was gathering all this data for use in their raw software and they decided to start the whole DxOMark thing to put that data to other uses.

Yes, but what can be measured with DxO Analyzer is not necessarily going to apply to what DxO raw conversions can do.  Just like what's measured by EPA for fuel economy (back calculated from emissions) does not mean you will get that mileage.
