Yes young leaves are different than leaves IN August.
Yet my young leaves on my Violette look different too compared to the above pix.
Please post a new Pix in August to see if you really have a Violette de Bordeau, identical to ours or not.
Only in August leaves take their final shape,and it is possible to ID,easier.
As a Matter of fact,I suspect you have a healthy,Black Ischia,missing Fig mosaic virus,and not Violette.
If it is what I think it is ,then you got a very good cultivar there.
