as with all things PS just try it out
this filter is most useful for images with dark areas that you need to bring
up without making complex selections and doing it by curves

If you have ever made a picture with the subject in foreground lit in full
sun,
where the background you saw with your eye had nice features but looks very
black on the capture,
that is a good one to use for your experiment.

as burnt (over-exposed) highlight areas usually have no pixels or image to
bring out, it is less successful for that, but the sliders give a LOT of
variations so use them and see what they do is best

Highlight detail is best by prevention of it in capture,
pay attention to that histogram in your camera
