At this point it appears that Dolby has managed to worm its way into the new ATSC 3 broadcast TV standard as well in the form of something called AC-4.
Dolby started as a tape hiss reduction system that actually was useful. Since that time it has more and more become just a way to extract license fees from companies making electronics that involve audio.
For the TV standard they could of just used the open Opus codec, but since the people who are creating the standards are the ones getting the licensing revenue there is no real incentive to do something like that. These "industry standards" have become a kind of a scam.
So no, Dolby is not all that interested in licensing software implementations of their codecs for random programs. That is simply not where the big money is and it isn't really their business.
