I remember another article that we moved away from skewmorphic design patterns because people understand that the things that the UI lives on a touchscreen and many of the cues for skewmorphic design aren't needed. Still some remain like for example settings are a set of gears. Before large screen smartphones people had to be trained on how to use it and skewmorphic design made more sense. What is needed though is visual cues though that work with flat design. Cards for example that can be swiped right or left. Turning up contrast can be changed by going into the accessibility part of settings but it seems like many accessibility features should be more apparent to more users because of its utility to a larger set of users.
