well , I think you need to brush up on some of those using UNIWB and Color correcting CC filter. The concept is that the sensor ( usually ) are more sensitive on the G level since there are twice of them vs the B and R photosites, and by switching to a UNIWB and utilizing CC filter to cut down to G exposure enough to put it on par with the R and B then its possible not to burn the G before the R and B also ramp up to the limit thus better utilizing all the Color DR.

Of course physically specking the sensor is not gaining any more DR, but its one of the technique to gain better Color accuracy and Spectral tonal spread ( Color DR if you would ).
