I think they are kind of lo-fi copycats of the RNI film profiles. The Fujifilm's Classic Neg looks suspiciously similar to the RNI's Fuji Pro 160ns while having visibly poorer quality in the shadows and dark skintones compared to RNI.
And the RNI profiles are definitely the best in class and built after the real emulsions very carefully, at least I can confirm that for Fuji Pro, Fuji Superia and Kodak Portra & Ektar - the stocks I'm very familiar with.
