It compensates for hearing deficiencies of the human hearing at listening levels below 85 db (reference level), where most sound tracks are been mixed originally, thus resulting in a statistically perceived "linear" frequency response for the listener at lower (below reference level) listening levels.
Because it does this in correspondence with the listener adjusted actual listening level it is labelled as "dynamic".
Has really nothing to do with your interpretation of "boosting".
PS.: There is a difference in terms of measuring and listening: if you are listening to a sound track your probably will have DynamicEQ engaged, but if you are measuring the response of the system, you probably will need to switch DynamicEQ off, because your mike doesn't have that deficiency problem of human hearing. It records rather "linearly", never mind the frequency deviations of your individual mike.
