Those two settings have very subtle effects. They are quite hard to understand and consequenty difficult to use.
I believe they adjust contrast in the highlight and/or shadow area by adding additional "kinks" in the contrast curve,
just as the regular contrast adjustment works by steepening or flattening the central "kink" in the contrast S-curve.
These two settings in question just control their respective kink in the highlight and shadow portion.
I guess you could use all three contrast adjustmenst in concert to put contrast where you want it for a particular
motive. For instance, to bring out lots of detail in the clouds, you would reduce shadow and regular contrast, and
increase highlight contrast, thereby making a steep and tall kink in the highlight part of the contrast S-curve.
The D-range settings do something else. Highlight protection lowers exposure by one stop behind the scenes and
lifts everything except the highlights one stop in processing.
Shadow protection just lifts the shadows in processing.
