It's a tradeoff: the Apple gamma may give more detail among darker
colors, but at the loss of detail among lighter ones. The default gamma
for Macs is so light that the whole thing looks washed out to me; the
first thing I do when I get a new Mac is make it readable by increasing
the gamma.

Ah, but, I would say the point is that the lighter values are
over-represented in the first place, gamma correction just helps to give
the shadows a bit more of a look-in.
When I used to teach Photoshop I would sometimes have students bring in
images they'd made on their PC's at home. They would be disgruntled
because their images looked all washed-out on the Mac.
Then I would have them examine the histogram of their image data, which
would always turn out to have no pixel values lower than about 35,35,35
and sometimes worse than that, nothing lower than 40 or 50. Why in that
case should the computer display any black?
Colour-management is supposed to get around these issues as far as
possible, and it does a great job when set up correctly. But in the
wider world where systems are generally uncalibrated, uncorrected, badly
adjusted, badly-sited, old, cheap, mobile and so on, it's rather
irrelevant. None of my equipment is what I'd consider calibrated in
fact, how about yours?
Only by eye: ever since I set my Mac's gamma to PC levels I can see so
many more details in the Mac OS that were completely washed out before. :)
I appreciate the background info on pro graphics. It helps to understand
a bit more about why Apple does the things it does. Sometimes it's not
just another case of the ol' light bulb joke. ;)
Not being a graphics pro, I don't care one way or the other what the
gamma's set to, as long as it's consistent across platforms. If Apple's
default setting is a better match to the real world, will PC
makers/Microsoft follow suit?
