What happens to the unlocked liveries after update?

Sometimes ago the devs did a survey about which livery do we prefer and would like to see in the game.

Since the update is not released yet, I am about to unlock the A388 EXPO livery using Gold Planes.
So, I am wondering what will happen to my EXPO livery if the devs decide to remove it?
Will I get to use the livery even after the update?
Will I get back my Golden Planes back?

Once the liveries are on the plane, they stay on the plane. There hasnt been an instance of a player livery being removed yet. Dont know why you thought they change each update, but that is your answer.

Unique liveries like the expo livery will probably not be removed by the devs.
