I kinda feel like I'm talking to myself here but anyway...hopefully this all helps someone...
Below is an screenshot of the same image (sRGB High res jpeg) opened in a colour managed and non-managed browser simply to demonstrate the relative difference. The browser you are viewing this in will determine which side looks better (in Firefox the left looks a little flat) In others the left is what I would call correct colours and the right is showing as oversaturated.
