Chris, glad to see you here.
"Dynamic EQ and Dolby Volume are solving completely different problems."
Per below cut-and-paste from Dolby site, DV is addressing loudness compensation as well as volume changes.
As you said, it does do it per freq band.
"Low-Volume Compensation
As volume decreases, human hearing becomes less sensitive to bass and treble. There have been many attempts to compensate for this, most notably the "loudness" button on many receivers.
The problem is that most low-volume compensation techniques simply (and inaccurately) apply a fixed bass and treble boost as you lower the volume. They don't take into account what's happening within the audio signal and individual frequency bands, nor do they account for content. This standardized approach can make explosions and car crashes sound muddy, while cymbals and laser blasts sound tinny.
Dolby Volume Diagram
Dolby Volume monitors and adjusts perceived loudness in up to 40 frequency bands per channel based on the content in those bands. It's far more intelligent than a simple bass and treble boost.
By monitoring discrete frequencies, and the content within those frequencies, Dolby Volume makes adjustments only where necessary. The result is a more natural, true-to-the-original listening experience all the time."
