Make sure you test some murky low-contrast material as well.  Most 
digital projectors appear to do well with high-contrast material, and 
tend to overwhelm your eyes so that it is difficult to see their 
failings.  Without a precise measuring instrument, you would not see 
that the blacks are gray or that the whites are blown-out.  That is 
why home theater stores play bright high-contrast material all the 
time, and murky low-contrast material is nowhere to be found.

One of the best dark transfers I have seen (at least in HD) is the 
film "Mimic" (http://www.imdb.com/title/tt0119675/).  The HD transfer 
is very clean given the overall darkness of the film, and should 
challenge any digital projection system.

If murky low-contrast material does not display well, then the display 
certainly can not be used for grading or serious evaluation since the 
region near black is very important to get right.
