True. But my observation of the DI is that it really doesn't cut down the iris very much until there is almost no light in the image, e.g., in a fade to black. It may be nice to see the screen get really dark in this situation, but it doesn't strike me as THAT important. With any light on the screen the DI is opened up, pretty much indistinguishable (to my non-expert eye) as having the iris at some fixed value.
However there are many people on the forum more knowledgeable about all this than I, and their opinion on this would probably be more worthwhile than mine.
