Even with the tree right infront of them an expert in Acers would probably struggle.
Spring colour/autumn colour, leaf size, stem colour, growth rate all need to be checked.
Some Acer palmatums are seed grown and do not have a cultivar name.
If your tree is grafted it may be a named cultivar...but there are 1000's
I also had an Acer obsession, I can warn you...it is not a cheap hobby.
Ladybird4 is right .
Love it and look after it...water it and mulch it well.
