Exported images have differing contrast and colour.

I've had this problem for quite a while and have no idea how it occured.

Exporting for web, images are higher in contrast and saturation than they are in Photoshop itself. I'm unable to show examples, because even when i save a screen cap of the original image inside photoshop, the saved file has the same result. Even the preview with web export is slightly different.

Color settings is the most obvious reason. Either embed profile in exported image or choose more simple and common color settings in PS.
