Definitely. I did an IL test render of an old scene using Streets of the Med, and the ground and building roof tiles are picking up light (a bit too much, actually) from the EnvSphere colour directly overhead, well out of camera view.
(Also in the same scene, P8 inverse square falloff lights are working really well).
