In general the W3C disagrees with most of that, and says that the
"sRGB" colorspace should be assumed as a best compromise.
In fact, sRGB is called "A Standard Default Color Space for the
"...HP and Microsoft propose an additional means of managing color
that is optimized to meet the needs of most users without the
overhead of carrying an ICC profile with the image: the addition to
the OS and the Internet of support for a Standard Color Space. Since
the image is in a known color space and the profile for that color
space would ship with the OS and browser, this enables the end users
to enjoy the benefits of color management without the overhead of
larger files. While it may be argued that profiles could buy slightly
higher color accuracy, we believe that the benefits of using a
standard color space far out-weigh the drawbacks for a wide range of
users. The migration of devices to natively support the standard
color space will further enhance the speed and quality of the user
and Microsoft says
"...In addition, both companies have worked with the World Wide Web
Consortium (W3C) to ensure that sRGB is available to all vendors.
sRGB has been the standard color space since HTML 3.2 and Cascading
Style Sheets (CSS) 1.0, and it is freely available to any software or
They've also made sRGB the centerpiece of their OS and color support
since Windows 98 and Windows 2000.

This I know from personal experience is untrue. Getting consistent
color is very important for professional web people (designers,
graphics creators, etc.) for video, for multimedia and for many other
things. Even a good Adobe-only web workflow involves the use of
various color profiles.
NEC also has info on this point:
"...In the future, sRGB can make a decisive improvement in the
possibilities for E-business and above all in the web auctions that
are becoming ever more popular. This is where the biggest advantage
of the new colour space lies. Even today, colour pictures on the web
are just as important, if not more important, as the reproductions in
"...It is impossible to completely iron out all the colour
differences between the various colour devices on the way from the
supplier to the customer´s monitor at home. But they can be
significantly reduced and thus displayed very realistically through
the definition of an optimum colour space specific to these
applications such as sRGB, which can also "understand" the different
devices and process them uniformly."
There is a lot more information out there, from many different
sources. However I figured info from the group in charge of web
standards, the company making the vast majority of end-users' OS, and
a company that is big in display hardware make up a good sampling to
get an idea of the state of the market.
