Return the pixel and color differences for an image comparison

There is currently no way to programmatically get the results of an image comparison. I.e. I would like to get the result of the pixel and color. I am creating a Region and check the difference, but would like to know the pixel and color differences. I know that I can use the Check method, to output them to the Log file, but in my case, I do not want check to output an error to the log if the images do not match.
