If you have a profiled monitor you experience that some CMS-aware aplications render the image to a monitor different from others.
ColorKeeper has built an interesting profile to test monitor rendering intent.
I've tested some applications with this test profile. The following applications use the perceptual rendering intent:
Adobe Lightroom
Mozilla Firefox
Apple Safari
Canon ZoomBrowser EX

The following applications use the colorimetric rendering intent:
Adobe Photoshop
Canon DPP

Safari and Firefox use CMS-aware features not only for rendering images, but also for rendering menu items.
