What proof we have that Aizen released Kyouka Suigetsu without a command? I mean, it was revealed that Aizen always had KS on during the FKT fights(which made their plan of preventing him from using it fail). He clearly used a command when using KS on Baraggan. And it's unknown if he didn't use it when demonstrating it to the Gotei soldiers.

Irrelevant, just because he sometimes uses the release command doesn't mean he cannot release his zanpakuto without it. By your logic Ukitake didn't ever reach bankai because he always released his zanpakuto with his summoning chant.
