HDRI Image Previews that indicate different exposures

Could someone tell me if there is a significance to the difference exposures shown in an HDRI preview such as the one attached.  I am familiar with loading an HDRI in DS and rotation of the dome.  However, the image below seems to indicate that I could have different lighting - but am too newb to know if it is accessable in DS.

Thanks for your time.

    Different settings in the Tone Mapping section of Render Settings, just as a photo will look different if you alter the exposure options.

    I think you will find that the lower picture is the images at different exposures used to make the HDRI in the top image. At 5 exposures that HDRI wont have a lot of light spread. A proper HDRI should go from nearly black to nearly all white over as many exposure increments as possible, at least 16 or more.

    Yes, on reflection it's most likely what Fishtales says.
