First off all… Why cant we use the Reflection Probe Cube Texture (rendered from the skybox mesh with Sky Material) be used as scene.environmentTexture

Second. how come there is no COLOR to tint the sky with… In Unity, for the procedure skybox you can select a color to tine the sky with
Third … is there a way to shoe night time with moonlight looking sky ?
If the cube texture of the probe is not attached to at least one reflectionTexture property of a material, it won’t be generated.
So, you can either set pbr.reflectionTexture = rp.cubeTexture or instruct manually the system that the cube texture should be generated by doing scene.customRenderTargets.push(rp.cubeTexture);:

Regarding tinting the sky, you can use the vertex colors of the cube:

As for your third question, you should be able to find a tint color that matches a night sky. As for adding the moon itself and some stars, I guess it’s not supported yet (but PRs are always welcome :).
The tint seems like it would work. Except is tints the whole sky mesh… should only tint the sky and not below horizon
