Using a Vaal orb on ingenuity belt divine question

So, if someone could help me out here please. I had 3 uncorrupted ingenuity belts which i used an Omen of Corruption followed by a vaal, all 3 the orginal value did not change, 44 72 and 76 got a enchant on all 3. I was under the assumption whilst corrupting a unique it got the effect of a divine then either a socket, enchant or a mod value multipiler but obviously i am wrong.
