Tangibly, "beautiful" UX is code for "rounded corners and lots of useless buffer space in between the informative elements". This is visible in the screenshots in the link. Things are further apart, less dense, and therefore more "beautiful".

I agree that OP's take is reductive and cynical. I would add that in this case, as in essentially every other case where this is done, it is also accurate.
