May just be particle effects

One of my favorite Orianna mechanics is hiding her ball in terrain to hide enemy team, but dark star Oris' ball has a lighting effect that no matter where I hide it you can always see it. I don't know if this is a bug or not but it's part of Oris' identity through my play style. If it is just particle effects wouldn't it make sense to turn the lighting off in terrain or hide ? The dark star skin doesn't even have added voice effects.
