Answer 1

I had a side menu/reveal controller (SWRevealController) which turns out to always be the root controller for status bar queries. Overriding childViewControllerForStatusBarStyle let me re-route the query to the front most controller.

/**
 This view is always considered the topmost for status bar color queries.
 Pass the query along to what we're showing in front.
 */
- (UIViewController *)childViewControllerForStatusBarStyle
{
    UIViewController *front = self.frontViewController;
    if ([front isKindOfClass:[UINavigationController class]])
        return ((UINavigationController*)front).topViewController;
    else
        return front;
}
