Very pretty indeed.

I assume you've looked at all the pics online you can find. What is different about yours?

For ID a side view and front view are needed. The side view should show the haft area as well as an opened fall. The front view shows any markings present on the standards. I would guess there are over 1000 lavender/purple plicatas registered. Where was it purchased? Would be good to get a picture of the stalk showing the branching. And measure from soil to top of terminal (top) flower. I keep this information in the jpg filename. IE, "noid yel 30in 2brnc dbl socket terminal".
