So far, on large areas I can see a difference between #404040 and both #3f3f3f and #414141 on the new 15" MacBook Pro. That rules out a naive 6 bit display. I think. The application of color profiles can could cause some regions of to have one-to-one mapping even if there aren't enough output codes available to cover the inputs, but I think with the 4:1 difference I can rule that out.

Here is a little web page I tossed up to help people screen LCDs. http://jim.studt.net/lcd-sleuth/ http://jim.studt.net/lcd-sleuth/ It will make a table with cells whose text is just slightly off of the background. You can stare are them and explore the limits of your visual system and your computer's display. (No one will be able to see all of the text on any statically adjusted display.) Additionally, on this MacBook Pro I looked at a greyscale gradient which I have used over the past and decided it was poorly distributed, so I ran through the color calibration (expert mode) in the Displays preferences pane. I ended up with a much better distributed gradient, but I introduced hue distortion so I didn't keep it. But there seems to be room for an improved profile.
