I have 2 Single Element Legend Element Dragons both of which are 1-star empowered. So, the Legacy Dragon is unlocked.

I have bred the Atlantean Dragon and Hope Dragon(both 1-star) several times and have still not obtained the Legacy Dragon.

Is the probability of obtaining the Empowered Exclusives of a certain rarity after unlocking them the same as obtaining a non-Empowered Exclusive Dragon of the same rarity?

i.e. Legacy Dragon is a Legendary Rarity Dragon. So if there was another offspring Dragon of the Legendary Rarity but it did not need empowerment to obtain it, would the probabilities of both these Dragons be the same.

Finally, is the probability of obtaining the Legacy Dragon by my method the same as obtaining it by the (Pure Dragon + Pure Dragon) method?

~ Appreciate the help.
