images in ColorThink question

I’m using the wonderful ColorThink Pro to help get my head around Color Management and to review my scanner profile.

One thing I just can’t understand is, why an image scanned with the scanner profile applied and embedded (and not yet converted to a working space) should be able to map colors in ColorThink that are outside of said scanners profile gamut?
I have found this with a number of images.

Surely, if it is scanned and embedded with profile “x” all colors within the image must lie within profile “x”?

Answers from color gurus, much, much appreciated!

I’m not a guru, but as I understand it an icc profile handles out-of-gamut colors with rendering intents. Since your image contained the scanner
profile, it must have contained one of these four intents…
