Does the displayScale of the traitCollection change while the app is running?

"traitCollectionDidChange(_:)" can handle changes in "iOS interface environment", but I don't think the "displayScale" of the previousTraitCollection will change. Is this correct?

Please let me know if there is an example where "displayScale" is changed while the application is running.

It may change when UIWindow is moved to a different (external) screen
