@pony you are thinking too much about it. Sure you are right when you start to dissect it. For others it's colours, textures, lights, etc. What other see are things like "royal space" --> luxury, "dimmed lights" --> cozy, "old architecture" --> conservative, upper-class and serious, those who recognise the space, or know it otherwise perhaps think "ours, national, us", etc. All the right keywords and branding for a president. What can you want more?
@pony If this makes you feel uneasy, I guess you wouldn't like to play Monument Valley (https://www.krasamo.com/game-design-inspiration-monument-valley-i-and-ii/) 🙂 - I admire and like that game a lot. Those screenshots came to my mind immediately when I saw the picture.
Anyway, I get what you mean. Could it be that you don't have mainstream tastes and emotional reactions? But then again, what do I know... Maybe most people indeed cringe when they see that setting. I don't. I'd call it "interesting" - as @piggo did too.
