ichigo didn't become a visored the same way they did, so in essense Aizen called them failures and ichigo more of a success because his visored abilities were semi natural even if it wasn't desired.

Most hollows masks are formed by there heart being removed and in visored cases it's basically apart of there instinct. When ichigo's powers were more instinct, as his eyes turning blue, he has incredible killing intent but ever since his awakening of his inner hollow taking over ichigo's power shifted from old man to the hollow ichigo in appearance in control. Which in turn made ichigo lose that edge he has previously, even Hollow Zangetsu, White, or whatever you want to call him, stated during ichigo obtaining his mask. Right now i think ichigo doesn't have the ability to call forth the mask as his powered were restored in a completely different fashion.

Anyway my theory is since using final getsuga tensho he lost the ability to do hollowification but his inner hollow still being present may just be because it's a fused state of white and zangetsu. I know this sounds confusing but if he had the ability to use it he'd have done so by now and sadly he hasn't thus why his profile page said it's former powers lol
