The perception of black depends on average image brightness, amount of
ambient light, structure of the image (where are the dark and bright
regions)... Excellent blacks in my books are blacks that pass the following
very tough test: 
- no ambient light, black room (minimal reflections from room on screen)
- space scene with black of space and some stars, mabe a little space ship
  too, not very bright
- the scene lasts long enough so the eye adapts to the very low average
  image brightness

Is space now pitch black or a shade of gray? If it's pitch black the blacks
are excellent. I have only seen this from top CRT technology. Laser should be
able to do it as well. Any technology that uses a bright lamp and takes
light away to create black will have huge problems to create real blacks
(and that includes film projection, DLP, LCD, D-ILA, LCOS).
