Welcome to Basenotes, Selina! I have three bottles of Kingdom at home, purchased at various times. I'll check the boxes and let you know.
I do doubt it though that anyone would have made the effort of creating a fake of Kingdom, it wasn't a really popular scent. As for why it could smell different: dabbing vs. spraying (as you already said), the amount you put on, worn in high vs. low temperatures, etc. Even my most-worn fragrances can show different facets from wear to wear.
Sometimes I do get an overwhelming amount of cumin out of Kingdom, at other times the cumin is a background player, lending the fragrance a beautiful, carnal warmth without making its presence really felt - so yes, even the fragrance sprayed out of the same bottle on the same person can change its face.
