If you have some printer ICC profile at hand, you can try to set this as the working colorspace. Then take a picture with highly saturated areas with some texture, and try to change the rendering intent. If the printer profile is of LUT type, you might see some visible differences: when the RGB channels are simply clipped by the relative colorimetric intent, the texture is probably destroyed or hardly visible. The use of a perceptual intent should allow to restore at least part of the original texture, because channel data is not simply clipped but modified in a more complex way.
Unfortunately I do not have a good sample image at hand to show what I am talking about…
