I do have both a K7 and K20, and it's obvious to me that the DR of the K7 is far better. It renders both more shadow detail and highlights and is particularly good on the hot end of the scale. I suspect it has more to do with the rendering firmware than the sensor, but I certainly can't say for sure.
