Well, in the Update Notes for "style unlocking" you could have read the items that can be unlocked right now. The devs also stated that they want to eventually make all styles unlockable. So it's not like the information is hidden. It's even in the "latest news" section of the launcher. If you just wait a bit you will eventually be able to just unlock the Luminous Gaze on all your other toons. Just bare in mind that it will probably cost 100-300 replay badges per toon.
