(Spoiler) Each Neo city has a different theme / focus?

My Neo stonk has reached the limit down so I'm just gonna try find more interesting things about them.

One ~~kinda obvious but since no one else is talking about it I'll do it~~ thing I noticed is the different theme / dress code between this new neo city and the Nineth City where Heidi and Rogen came from. The latter is a lot more visual and artsy in terms of the designs of their architecture and clothing, whereas this new city is a lot more formal / structured.

I'm not an avid reader of OPM so Idk if ONE loves to bury cues in these elements like Oda likes to do. But if this design is intentional, it could mean more interesting possibilities. For example, does the theme of the city somewhat correspond to what their citizens do?

Earlier, when Ario led giants to the 9th City and Parasites consequently showed up, the Neos in the crowd smiled and said "we got new toys". That was one of the only few times where Neos showed emotion. That, plus the scene in this latest chapter where Helim asked if his secretary felt fear, to which she answered "unfortunately", give me the impression that Neos are actively seeking to experience emotions / stimulation. So, the purpose of the 9th City might be that, they are exploring for possible ways to stimulate emotions. As for this new city, their leader's title was "Director of Legal Affairs", which is quite obvious what he specializes in, and it also more or less corresponds to the suit-n-tie theme of the city.
