My husband is white and he always prefers an asian looking woman, despite he grew up in a place where there was literally no asian people. It was interesting during one of the trips to his hometown. His sister organized a huge party for their father's birthday. A few people came to me to introduce themselves. I eventually asked them how do you know I am his wife? They all said we knew he married an Asian girl. That is enough to identify me in a party of over hundreds. On the other hand, I am an asian who always find a man with blue eyes very attractive, despite I grew up in a place no white man ever lived there. Our adult sons definitely prefer white/spanic looking girls. I do not think it is just culture endoctrine.
