Are these 3 Acer platanoides cultivars actually the same tree?

I saw a specimen of -Acer platanoides- 'Palmatifidum' today at The Royal Botanic Gardens Edinburgh and immediately fell in love with the leaf shape, however after looking it up online and in the limited selection of books I own it appears to be somewhat identical to -A. plantanoides- 'Dissectum' and also -A. platanoides- 'Lorbergii' is this the case? or are they all separate cultivars in there own right?
Thanks in advance!
