I've even noticed I think worse in that sort of environment. Like I'll look at things I wrote in a high-density area and they look like insane ramblings.
That doesn't seem to be a 'well, you just need to find a nice high-density area' problem. I've lived in some very well-appointed flats in very nice areas before, and didn't care for the experience in the slightest. I don't care whether the flat's fantastically appointed with real oak furniture and good lighting[1].
And what are we offered in return for that unpleasant sensation? I don't care how many coffee shops or restaurants or whatever there are. I don't go to town unless there's something I can't buy on the internet or I need to go to work. There's little I'd value there. Rampant consumerism is not a society, nor is it a community. The ability to shop in a hundred stores is not the same as a high quality of life.
Ultimately, that is why I don't live in a high-density area despite being offered several multiples of my current wage to do so. I make enough to be comfortable here, it would be almost impossible for me to make enough to be comfortable there.

1. Which, by the way, is very difficult in a high-density area. Good lighting means light from multiple directions in at least some of the rooms. Quite how you're supposed to do that when there's another building in the way I'm not clear on - the general answer seems to be that one doesn't.
If you've lived in a property with good lighting angles some practices, such as an open-plan setup seem rather like bad hacks.
