I also agree that it looks a lot nicer because of the high-end stock photos.
Edit: scrolling down further, there are some other UI refreshes that I do think improve the experience overall - the calendar and photo album views stood out to me. But I think it's important to use ugly people with weird names in your designs to gauge how it will actually look in production! The dark theme on pages, for example, looks very clean with Apple and Adobe as featured, but I imagine will look pretty dreary to stare at all day.
