What are the possibilities on Windows Lockscreen?

[Rhialto]

I just found out my K70 LUX RGB MX SILENT (yes!) have a memory to store a default profile. So from the default red keys except WASD in white I was able to set another static color. I tried to store an animated effet like Rainbow or Wave but it does not work. I understand I cannot have multiple effects stacked and stored thought.

Am I limited to a static color when the Windows Lockscreen is active?
