Here are a number of additional images, including the first one, of Nancy dancing, from Sin City. Very good detail in the dark walls, and you can make out objects on the shelf on the right.
You'll note that in the image above, from Phantom, the BenQ W10000 projector does an especially good job of providing shadow detail in the glove and the top of his coat, compared to other projectors where I have provided the same image.
I also call your attention to the first image from Phantom (the 5th image in the flesh tones section above), which is also repeated about two paragraphs below. Another good place to look for shadow detail is on the left side, you can make out faces and more. Since this image is on all reviews since mid-summer, you can easily compare.
