User blog:DivinitasX/Wings = New Earring?

After watching Rei perform I noticed something, that kind of made me laugh a bit and I confirmed it with Aria's performance. I haven't checked each of the idols, maybe someone can to see if that is the case for all.

So, my big revelation: It seems that if an idol gets her constellation wings her left earring changes.

It's becoming a circle representing the icons on the "wings cards".

(Also apologies in advance if there already is a post about this.)
