Yes, aesthesia makes a very important point. Uber/Lyft & Co. standardized the UX just like you can expect what a Big Mac tastes like at any McDonalds in the world.
It's not just homogeneity. Cab and car services basically didn't exist in many US cities prior to ride sharing. I'm a carless transit fanatic, but 10 years ago I'd probably have to buy a car to live comfortably in my current neighborhood.
