The page that I make start-page always loses its horisontal blue top bar. Even if it has the same template as all other pages. You can see it on http://www.quadriga.nu
Yes page title will not be displayed on the home page. We have designed our theme this way. To add horizontal blue bar, it needs code customization as this is a new feature to be added in the theme.
You can try using Home Slogan Options. Go to dashboard -> appearance -> customize -> advanced options -> home slogan options.
