I think Yume forgetting her (gigantic) rainbow aura was with the same reason for Ichigo and her Special Appeal. Something like adrenaline, the thrill of being onstage, and Yume was even more determined and inspired than usual (this being her first solo live, and because Sensei Subaru had been such a great advisor as usual), so she was even more focused on bringing a great stage for her audience.

Her performing her aura was a nice touch to the performance, but part of me hopes it won't appear again until another "special episode" comes up. It would seem a bit too soon to have that gigantic rainbow appearing on a still fairly new idol's performance every time. I think I'd like for Yume to finally "master" it possibly around the end of season one, just to show exactly how much she's improved over time and make for a dramatic finale.
