I am trying to customize how to set the iOS 10 background / widget today to what seems like dark mode by default. In the image below, you see the Metro Weather widget today, and it's dark. There are several applications with a dark background, and all of them are similar to the same background / style, so I think that it can be a certain dark mode that can be set in the code, and not just play with the controller color / transparency - it doesn’t matter as far as I try to set color and transparency manually in the story panel, I can't even get close to this effect.
