Since we didn't have the two projectors at the same time, no side by sides, but here are some good black level images. Two from the JVC DLA-RS25, followed by two from the JVC DLA-RS35:
The satellite scenes is heavily overexposed to make it easier to compare black level performance. Unfortunately.
The exposures are never exactly the same, making it hard to detect slight differences in black performance.
Below is the same image from Space Cowboys (on Blu-ray disc) but more overexposed, to make it easier for you to see the difference in black levels.
