There is a precedence in the order of tags. If A2B1 is not found, then it reverts to A2B0. If none of such tags are found, then it reverts to matrix-shaper (colorants and tone curves). I'm unsure if this is stated in the ICC spec, but AFAIK all CMM does behave alike. There are some profiles that instead of implementing all intents just "link" the A2B0, A2B1 and A2B2 to the same table, which usually is relative colorimetric. So the bottom line is: you cannot know in advance whatever gamut mapping is being applied. It is up to the profile creator. That may be frustrating but is inherent in the ICC way to do color management.
