It’s the movie. It’s been criticized before for being very darkly lit.
In regards to including the Imperial Cadet scene, I think the scene in the Tie fighter is probably not good since it has unfinished FX.
But the court tribunal scene I think could be a valuable insight into Han’s character and how he doesn’t really fit in a structure, being a rebel by nature. Also I think it can stand alone without the setup since Han essentially explains what the incident was.
