For best results, use a bracketed HDRI with multiple Exposure Values.

Can you please explain what that means?

For an HDRI to effectively light up a scene, it should be a composite of the same image (in one file) taken at different exposure values (EVs).  Multiple-EV HDRIs will therefore illuminated the scene without any need for additional scene lights.   The quickest way to tell if an equirectangular HDRI file is a single-EV file is when the image is used as 360 background but the scene is still dull and poorly lit.  It must to be equirectangular, because it maps onto a spherical dome to enclose the scene.  An equirectangular image has proportions of Width: Height in the ration 2:1.
