Hello, the subject is indeed complex and camera manufacturers do not address it even in their equipment manuals. In my opinion, the main advantage is that you can recover highlights during editing. A practical example is recording a full moon after sunset, when the moonlight is much more intense than the brightness of the landscape. By using a lower ISO, you can recover both the moonlight and the landscape light during editing. Best regards.

Thanks for the great example!

For anyone in the comments wondering a good use case for this would be for something like astrophotography where stars are obviously very bright. You can actually shoot at the second base ISO of your camera, ensure you get sharp stars, and make sure you don't blow out highlights and bring up the exposure again in post. This will ensure you preserve those highlight details. Normally I wouldn't do a whole shoot like this, but the last several frames of a composition I will do this just so I have some backup frames in case I made some mistake with the "normally" shot frames. It is also great for blue hour blends to push later into blue hour giving a much "flatter" image that will blend much easier with a milky way shot.
