There in lies the problem...a wide gamut display without color management will ALWAY over saturate your images in most web browsers...the ONLY wat to view what 99% of the wold's population will be seeing is to switch your high end display to emulate sRGB
Actually there is a way, but only using Firefox:
in the adress field, and scroll down to gfx.color_management.mode.
The default value is 2, which means Firefox will color manage tagged content, but send anything untagged straight through to the display. With a wide gamut monitor that means it will appear oversaturated.
If you change the value to 1, something interesting happens. Firefox will now assign sRGB
to any untagged material. That enables color management to get to work, and convert to the display profile. The net effect is even better than using an sRGB monitor (which will display untagged material correctly only insofar as the monitor space matches sRGB exactly), because now everything
will be properly color managed for the display. Assuming of course that untagged images are created in sRGB.
I know of no other browser where this is possible. Safari doesn't have this "switch" AFAIK. Don't know about Chrome. And the less said about Internet Explorer the better (they decided in their wisdom to convert everything to sRGB, but ignore the display profile. On a wide gamut monitor that means everything
is oversaturated, tagged or no tagged).
