Identification: What acer palmatum atrolineare cultivar is it?

Hi,

in the sellout last year i bougt an acer palmatum without identification tag. It is an atrolineare type, but i don´t have a clue what cultivar.
In spring color is reddish, in summer it turns green and the fall color is yellow to orange.

I added pictures of Spring, Fall and Summer (only in dried condition).
Could someone give me an identification for this tree?
Could it be a villa taranto?

Greetings Raino

 

It doesn't look like a villa taranto.

 

Any other idea?

 

Astrolineare!:)
