I'm not sure what you mean by camera as opposed to sensor. Everyone uses the camera in order to test the sensor. Sometimes results are stated for a particular camera & lens combination. Usually that's done for lens testing rather than sensor testing.
Sensorgen definitely sets their data from DxOMark. I do something similar with DxOMark data but don't publish my results.
It's unclear to me whether DxOMark actually collects "good" data. On paper they have very good "protocols". But in truth the data they expose at the web site is not suitable for sensor analysis. Both Sensorgen and myself often get "screwy" numbers when using DxOMark data. (FWIW I have made inquiries at DxOMark but they go without reply.)
If you were going to compare Photographic Dynamic Range (PDR) with anything it would be with the DxOMark Landscape Dynamic Range. They compare quite favorably only they are on different scales.
The Sensorgen numbers are "engineering" dynamic range. So even if I trusted them they would not be right for comparing to PDR.
