Indeed, I have to really come back in at a low rpm (sub-1,000) before I hear the auto-throttle take over and get a touch of rattle.

I think your 5.9L probably has pretty similar clutch engagement torque as the 6.7L. I'd say over 350 ft-lbs easily.
Regarding the "auto-throttle" you're correct. The low-speed governor will not engage until you dip below the idle speed. For me that's 800 rpm. I think it's the same for you. Basically the low-speed governor is there to prevent stalling--if you load up the engine so much that the speed dips under idle speed it adds more fueling to try to get the speed back up to at least idle speed. Of course, it can only do so much. If you try to start off from a dead stop in 4th gear and just dump the clutch it'll stall anyway, because it can't react that fast.
