At least with the "f*ck" books this is just a money grab. Subtle art was a hit - I also remember enjoying the book - and it sprung bunch of copy cats with no originality. I also got suckered into this, picking up another one of these books thinking it was a sequel, but it was the most boring non-sense and I dropped it almost immediately.

I suspect money drives most other of these trends. You want to builds homes to look away that is proven to get highest sale price. You want to make the car look like the model that has sold most over past decade. You want to make your coffee shop look like what a successful coffee shop looks like to attract more customers. You want to make you influencer account look like every other influencer account to get as much sponsor and ad revenue as possible.

This is the same reason why we see reboot after reboot and if it isn't a reboot it is a sequel or prequel or reimagining of some sort, since all of the arts are now investments and need to make profit, no one wants to take a risk on unproven idea.

As for why even my home has white walls? Most people don't change the default. I don't care enough about the wall color and I know that I will be selling at some point and would have to paint the walls white again.
