I would think it might be the opposite. I feel like the darkness could bring more anonymity which could actually have fans be more inclined to act crazy. I mean, look at cause and effect of anonymity in social media...
For fans in the colliseum I could see this being where the balcony likes it and sees improvement(same small can lighting up there, improved court visibility). Whereas, the lower levels may feel the opposite(less light bleeding from court lights for dimmer seats but much closer to the brighter/harsher? court lighting

)
I fall in the balcony catagory and really like it.
Also, I see where a fair amount of the new lights weren't in use and they can probably expand the lighting footprint out if they every need to. Or, maybe some of those are pointed at player entrance for intros. A spotlight-ish setup possibly? I'll be interested to hear what they do for the opener and get your guy's feedback as I can't make it. I would bet they saved all of the cool new stuff like that for the first real game.
