My guess would be that the reason why Uiharu's appearance changed is related to the Angel Dragon's Ability. Like maybe it can make those that are on the brink between Light and Dark switch over to the other side. Though I honestly hope that this isn't the case and that it is related to Uiharu's own Ability. What I think we can say with absolute certainty though is that it is not just an artistic effect as there's a panel specifically pointing out the appearance of the markings that start appearing on her skin.
