Apple has improved the design of the App Store, which clearly has the feel of iOS 11 which was launches in September last year. Though the feature of App discovery is missing, but then new web-design does pack a punch.
The new design feels very fresh and exciting with more of white spaces, and also more emphasis on app reviews. Looks neat and much better than before, gives the user a good first impression on opening the App Store.
Also, if the App is specifically optimised for iPhone X you can see iPhone X screenshots in the App Store. Apple also has a reminder feature where it reminds the user that the Apps are only available on the App Store for iOS devices.
