Applying the Image Processing using the Default Rendering Pipeline, in a combined scene, with meshes/PBR materials and a Gaussian Splat model delivers different behavior for each part.
Do we need to do some color/gammaspace conversion for the splats?
I have applied the Default pipeline to the Docu PG.
As you can see the Splats do bvecome very bright even with the default values.
In our scene, the same happens.
