Interesting. I did a few tests and it appears that CKFinder has problems in IE9 when uploading CMYK pics via the dialog's Upload tab > Send it to the Server button. When I click on Browse Server then use the Upload button, it works fine. I suggest using the latter method for now until we sort it out.
First of all, you must remember that CMYK images aren't supported in IE until IE9, so usually it's not a good idea to upload such images to a web page.
Second, the biggest data loss that I see on your image is that the original is 3008x3577 and the downloaded one is 1892x2250, that's a lot of pixels lost along the way!
If you adjust the configuration so that the images are not resized I think that the color space won't be changed and you'll have really the original images instead of a downsampled version.
