Variations in Neofinetia fragrance

Neofinetia have been coming into bloom since a month ago. They emit my favourite floral fragrance, (that says a lot as I am normally loath to pick favourites of anything).

Over the years I have noticed interesting variations in fragrance between clones of the species. The 'standard' whites such as 'Amami Island White' and 'Gojō Fukurin' have what I would call a 'clean' scent and yellows such as 'Kibana Fuuran' have a more 'fruity' scent. Tonight I noticed for the first time that 'Amami Akabana' also has a different scent, it is more 'buttery'.

Have any of you Fuuran lovers also noticed these differences in fragrance?

I haven't managed pictures of this years' Neofinetia blooms yet but here are last years' 'Amami Akabana':
