Actually, there's plenty of insight there.
We've seen Demacia's upper class, but Quinn is the first exploration of the lower class of Demacia that we've encountered. Her reminiscence about Caleb reveals that they wanted to gain "honor" - something that seems to be restricted from the lower class/peasants.
We also get to see a bit more of the way Demacia is run. Much like your Renaissance Fair, decrees from the King are written/printed and posted throughout the city and surrounding areas under Demacian rule, and the moral standards of Demacia create a pressure on people to act.
Quinn's journal even develops more of Garen and Jarvan IV's lore - by characterizing their reaction to her suspicions about Talon/the decree, we are given more insight into Garen's trust of the crown, and Jarvan IV's more Solomonic nature.
