Is "new lighting" from WWDC22 used only in AR Quick Look?

Is the "new lighting" introduced in WWDC22 "Explore USD tools and rendering" implemented only in AR Quick Look or has it become an integral part of the SceneKit and RealityKit rendering engines?

The "new lighting" in AR Quick Look changes the image based light source. Similar adjustments can be made to SceneKit and RealityKit with lightingEnvironment and lighting, respectively.

I understand that the "new lighting" feature also adjusts "contrast", which is not adjusted by "lighting" and "lightingEnvironment".

How would I adjust scene contrast in SceneKit and RelityKit as it is done in AR Quick Look?
