If the intention is for ICC profiles to be useful for imagery, then they are wrong, and it's easy to confirm that they are wrong - you just have to take one look at an image printed on tinted media - I have a bunch of examples from our local TV guide, which (used to be) printed on green paper. Even though the paper is obviously green, the highlights of photos look white (the human visual system is marvelously adaptable). If we were always adapted to the illuminant, then displays would look all wrong - the D65 white point of a display rarely matches the local illuminant. Besides which, no-one normally looks at the illuminant - it will be bright and glary. Normally you can only see it indirectly, such as from the thing that is primarily occupying your field of view - i.e. the paper stock.
