     Climbing the class hierarchy from MetalTextFieldUI up to
BasicTextFieldUI, I find the method

     /**
      * Fetches the name used as a key to lookup properties through the
      * UIManager.  This is used as a prefix to all the standard
      * text properties.
      *
      * @return the name ("TextField")
      */
     protected String getPropertyPrefix() {
         return "TextField";
     }

... which sort of looks like what you're after.  (But I haven't
researched any other delegate classes, so it's possible they're
different.)
