Hmmm, I didn't specifically look at the black levels when I viewed the display from various angles, but I did read in the 9-series thread here on AVS that some people noticed the blacks getting greyer in such cases. That's disappointing to hear, but I don't think it's quite as severe as people are making it sound just slightly off center. The other night, when I was viewing this display at Best Buy, I was getting up/down, and moving slightly side-to-side (because of where the bench was located), and I was continually impressed with the contrast and black levels. I'm sure that if I went back and looked for it a little harder, I might notice it, but it's not anywhere -close- to the same greys that you get on displays like the one that I own (a CCFL LCD).
As far as motion goes ... yes, the AMP does look a little bit unnatural, but IMO, its smoothness actually makes it feel more natural. The only unnatural feeling I get from it is that it seems like it's making all of the motion too fast. If it were somehow altered to not have this effect, but still smooth the frames together, I think it would be better. There is certainly room for improvement in this feature.
I guess I really would have to sit down and watch one of those films on a Kuro to get the best impression of both displays. If I get the opportunity to do so, I will, but I don't know if I'll be able to. The Kuro they had at my local Best Buy was mounted high up on a wall, hooked up to one of their signal distributors. Therefore, the video quality was inherently worse than if it were hooked up to a native HD-DVD or Blu-Ray source. On top of that, the lighting out on the floor, outside the Magnolia area, is crap for watching video content.
I'm willing to give the Kuro a chance I guess, but I still don't like how dark it is, relative to the 950.
Edit: While I have little doubt that Sony makes a good LED LCD, the XBR8 is horrifically over-priced (not that the Samsung isn't, but damn).
