I haven't yet used an HDRI image/image_map in a scene, but I would assume that
the maximum rendered brightness on-screen would be clipped to 1.0 (typical
maximum white)-- or rather, as bright as your monitor can reproduce 1.0, just
like with any scene.

The saved file is another matter, if it's saved as HDRI. (POV-Ray can do that,
right? I haven't read the documentation enough to know.)
