please check if your rendering intent is eighter set to photografic or 
relative colorimetric with black point compensation activated.

As well AdobeRGB is rather large. You will not be able to convert any 
colours near the RGB primaries (red, green, blue) into ISOcoated without 
gamut compression (partitial desaturation).

Lightness will be changed for the high lights and dark areas. Thats due to 
the ISOcoated gamut as well. You can see the gamut here:

To mark the moved colours in your picture try mark_out_of_gamut or 
similiar option.
