How to load a resource depending on UIUserInterfaceStyle

Say I have a TVML app where I have implemented a custom placeholder like so:

<img style="tv-placeholder: my-placeholder" />

and my custom interface creator:

class MyExtendedInterfaceCreator: NSObject, TVInterfaceCreating {
    override init() {
        super.init()
    }
    
    func resourceImage(name resourceName: String) -> UIImage? {
        if resourceName == "my-placeholder" {
            return UIImage(named: "placeholders/my-placeholder")
        }
        
        return nil
    }
}

How do I change this code such that I can return a different placeholder if the UIUserInterfaceStyle is 'light' or 'dark'?
