I noticed that the iOS app, Things, has a status bar with grey content (not black, or white) in their iPhone app. I noticed this on an iPhone X. I was under the impression that you could only have a status bar with black or white content by setting the status bar style.
See the attached screenshot for an example.
How would they have achieved this in their app?
Edit: I do not mean the background color of the status bar, I mean the actual color of the text and icons in the status bar.
