Well for a start, the issue with Blade's helmet isn't solely limited to Zi-O, it's also present in Super Hero Taisen GP and Gorider. And the consensus among most people is that the Ace helmet (along with Garren) has suffered from colour degradation due to the see-through plastic used. So it wasn't a deliberate change, but something the producers had no control over.
