Ray tracing isn't necessarily about creating "realistic" scenes. It's about creating a realistic model for the behavior of light. It doesn't preclude color grading or any other stylistic flair you want to inject into a final render. Fortnite is a cartoony game that looks pretty great with raytracing. Epic's Matrix demo adopts the same "cold blue" aesthetic from the films. Disney/Pixar use path tracing in their 3D works but nobody would say "Up" or "Frozen" look "realistic", you know?
