Just for information: For technical reasons, POV-Ray can only use the
Oren-Nayar and Lommel-Seeliger models for direct illumination from
conventional light sources. The radiosity algorithm computing the
indirect illumination needs to use a Lambertian approximation instead.

So in your image, using the Oren-Nayar model will only make a noticeable
difference where the walls are directly lit by sunlight.
