    How that cmyk profile is shown depends on the image viewing app too and if it [the app] can show that colour profile. Have you tried opening the image in a webbrowser, if it's updated and your monitor has the specs for it, try drag&drop the image to an open browser tab. As for img viewing app you can try nomacs.
