I believe that his hollowfication has been removed, his inner hollow stated that he was his instinct and if you remember he only obtained that hollow mask trying to regain his lost powers thanks to Captain Kuchiki around episode 17. I think Ichigo having the mask was a mistake so with him having his shinigami powers i think his powers and his instinct are all there, meaning he won't fight enemies with logic but just effectively killing them like he did with Ginjo. He didn't hesitate for one moment when slaying him. That's my theory anyway

However seeing how the hollow white melded together with his zanpakuto zangetsu, as ichigo stated he is zangetsu much like the old man.
