Some do, some don't.

Safari, for instance, does. If there's no embedded color profile, the
1.0.x versions of Safari assume the monitor's profile (which is a pretty
stupid thing to do). In 2.0.x, Safari assumes sRGB unless told otherwise
by the image file.

Other browsers do things differently.

So: The best practice when it comes to color on the web: Convert your
image to sRGB. Embed a color profile into it when you save it (PS has a
check box for this). And keep in mind that services like Flickr will
often scale the image locally and ignore the color profile. If you could
assume all elements in the chain were color managed, then any old
profile would do. But you can't, so it won't. :-)

If it's an actual photograph and it ends up on Flickr (or even on my own
gallery), I'm less concerned with actual color values and more concerned
with relative color values. I never Save For Web if it's a photograph,
anyway; I just want a max. quality JPEG.

But for web graphics where a range of color is meant to match with a hex
color on the page (a heading graphic for example), some of these color
management issues do rear their ugly heads.

All I am doing is offering my experience with sRGB and Generic RGB with
regard to saving web GRAPHICS (not photographs!) and the Save For Web
function.

Hi

I noticed you mentioning Generic RGB, what is that?

I don't see a profile anywhere for Generic. sRGB and all sorts of other RGB
but no Generic.
