There are several modes that seem to be unusable with real life light values.

1) Light Hierarchy Debug Mode doesn't work. Hard to tell if they dont work or exposure issue. No matter what you select, you get a white render. Even if you select light types that are not in the scene. Like Direct Tube in HDRP template.
2) Baked Diffuse Lighting has the same issue. Overexposed and hard to see.
