Dirac Live has been out for years and is used in pro circles as well as consumer electronics, it is a very advanced system and is not the easiest to set up, but when done well can be game changing, (Best to leave it to your dealer rather than trying to set it up yourself) it is used more by smaller manufactures rather than the big boys, (Although as Arcam is now owned by Harmon it is getting wider use in other products in the group) as to whether the big boys decide to obtain a licence to use Dirac then probably not as they are heavily invested in their own systems (Even though most their room correction systems are not very good) plus they tend to go for plug & play.
As always room correction should be the last thing to set up, with the first being acoustic treatment of the room as much as possible, with room correction adding the icing on the cake.
Will it work in your room? Then the answer is yes (Just like all room corrections systems) however how good it will be will depend on the room and its treatment. (Room correction systems are not a miracle cure)
