Some perfume ingredients have had to be changed. Either they came from endangered species, or they have become exorbitantly expensive. Some chemical ingredients may have replaced some natural ones. It may be that you are particularly sensitive to the changed ingredient/s. Most "noses" - the people who specialise in perfumes in perfume houses, are male, but it is well known that women and men sometimes get different sensations from the same ingredient. ( Such as cedarwood.) You may have picked up a difference which the "noses" have not realised would be noticeable.
