The damages screenshots came from the "test your strenght" thing that came on every second week of raid bosses event. It's a 10 turns fight with an infinite HP boss. You got extra event currency for doing a certain amount of damage. But with monsters like Cattleya, you do way more damages on the first fight than the total needed on a week and the fight turn into a showcase of most efficient team build to reach insane amount of damages. Useless but very fun.
