This is his proof that this tv has a 6000:1 contrast ratio. I think its just careful wording by Sony.
3LCD technology builds on the best LCD technology (active matrix), the best active-matrix projection technology (HTPS), and microdisplays to give you a small projection device with sharp detail, bright picture quality, and great color contrast. 3LCD technology is the most widely used technology for projection systems.
3LCD delivers a fully rendered color picture (composed of primary colors - red, green, blue) to the screen simultaneously. The result of this is called color breaking, which manifests itself as an RGB halo when bright images appear against dark backgrounds and other conditions.
3LCD projection is gentle on the eyes. With 3LCD, you can see subtle color variations and hues without distortion in a wide range of colors, which gives the projected image a natural appearance. Because 3LCD technology uses a three-LCD panel system, like HTPS projection, the primary colors remain unique. Dark and light values show distinction and appear life-like.
3LCD uses a higher-contrast ratio to provide sharp detail. Contrast ratios measure the degree of difference between the bright and dark areas of an image. Images projected with insufficient contrast appear hazy and lack sharp distinctness. The better LCD panels have a contrast ratio of 700:1 or 1000:1 at the top of the line. 3LCD technology makes a 6000:1 contrast ratio possible.
Contrast ratios are influenced by the brightness of the room used for projection.
3LCD projection is gentle on the eyes and maintains the integrity of the displayed image in even the brightest rooms.

Most are not accurate at all. Basically just manufacturer's PR blurbs. Sets advertising 5,000 or 10,000 to 1 in reality, when measured by an independent 3rd party probably won't come close to even 3,000 to 1
