  As long as leds can produce 256 shades, the law firm is wrong and Apple has no reason not to advertise with it.
  I sure hope they understand the difference between colors a monitor can produce and the colors the human eye/brain can distinguish...

  The ability to detect color differences is more pronounced in some areas of the spectrum than others. Darker and less saturated colors tend to show more banding.
  
  The root of the problem is that the eye responds to color logarithmically, not linearly, and displays/color spaces are mostly linear. There are some perceptual color spaces, but they're computationally more difficult, and are generally not used outside of research.

  With iMac's screen resolution, simply making a horizontal vector graphic gradation across the entire screen (like blue to red) would make the difference between 32bit full colour and 16bit pretty obvious.
  
  I mean, it's apparent even on my MBP laptop screen.

  200 gradations of hue x 20 levels of saturation x 500 levels of brightness = 2 million gradations
  
  One must assume these numbers are approximate, but the eye is physically capable of detecting a lot more than 200,000 colors. On the other hand, it would not be capable of detecting the advertised number anyway.
