In a highly idealized (and unlikely) sense, including a truely colorless scene and a highly frequency-selective filter in front as well as orthogonal CFA filtering, you could use a bayer-sensor camera featuring N stops of DR natively, to capture 3xN stops by shifting the different color channels in respect to each other.

In a more practical sense, "inter-channel exposure variation" allows you to recover some luminance details in the extreme highlights and shadows, that might be impossible if the channels had been perfectly equalised.
