The correct way of implementing chromatic aberration would be like the one on the “corrected” side. There is still some, but it really is subtle.
Anyway, I don’t think games are a good target for chromatic aberration. It’s really meant for photorealistic scenes, mainly photorealistic renders, that give a sort of uncanny valley effect without it.
But once again - it looks stupid if your scene is not photo-realistic in the first place.
