We should notice that non-fullscreen modalVC CAN use modalPresentationCapturesStatusBarAppearance to control the statusBar style.

Anyone who wanna know more about Status Bar control should not ignore the UIViewController Managing the Status Bar.

And make sure you have set UIViewControllerBasedStatusBarAppearance described in iOS Keys

I noticed that viewController in a navController may not get call prefersStatusBarHidden with iOS 10.0 - 10.2. Custom your navigationController to ensure that

@implementation YourCustomNavController
//for iOS 10.0 - iOS 10.2
- (BOOL)prefersStatusBarHidden {
    UIViewController *childVC = [self childViewControllerForStatusBarHidden];
    if (childVC) {
        return [childVC prefersStatusBarHidden];
    }
    return [super prefersStatusBarHidden];
}
@end

And anyone who want to go deeper inside can dig into UIKit +[UIViewController _currentStatusBarStyleViewController] using Hopper or IDA Pro. It may helps you solve these kinds of bugs.
