Actually, the quantity of "!" in your background depends on how many times you've finished the 100th floor of UTC event before. So if you've finished the other 2 events before you'll receive the background with "!'!'!".

I haven't cleared floor 100th yet, but in the last UTC event I got the background with "!'"' since I didn't participate in the first one. I'll probably receive the one with "!!" this time.
