Thanks for the link. I see green in Chrome and red in IE.
My wild guess: Most systems have a normal gamut (sRGB) profile loaded. On calibrated systems a calibrated sRGB profile is used. If a browser sends a jpg to the OS it uses sRGB. If a browser like chrome detects a jpg with a profile it enables color management. An image saved as sRGB renders identically on a normal gamut system (calibrated or not). This would suggest Windows uses the calibrated sRGB profile. On wide gamut systems a browser like chrome does the same trick. The problem is a jpg without a profile, the OS handles the image and renders an over saturated image because the OS doesn't use color management (very strange). Calibrating a wide gamut system results in correct colors in apps like LR, PS etc en correct colors in Chrome if the jpg is presented to the browser with EXIF available. If EXIF is stripped by the webserver the colors are wrong in every browser.
