Regular operatic structure is something like this :
Firstly, we'll have an overture. Dystopian Overture won't be 2 min short, it will probably be much longer, as it presents many of the themes, and the "feel" to the whole album. Overtures are generally something like first movement of the symphony. After that, we will have scenes, every scene usually consists of recitative (spoken, narrative part), aria (which has song structure, more melodic, it is sung by characters as a reaction to recitative) and chorus (reaction of a choir (resembles community) to the events).
I guess you can conclude from the tracklist what will be narrative and what won't. Those scenes (like 5 of them) form an act.
I also guess DT added NOMAC symbols next to tracks to symbolise a new point of view: machine's.
Also, there is a decent chance DT included real choir in the recording
