I recently replaced my king with another lion so that he has better heritage/stats but the same markings and appearance

I kept the name since I want to keep the "same" lion but I'm wondering if it affects if a lion is dirty

this cub's mother was bred from the first king but was bred to the new one. this makes the heritage look dirty because of the name but the game says its clean. for future reference would cubs like this be considered dirty by players because of the name or clean because of the genetics
