We are able to get the deviceWidth/Height and deviceDPI in WebKitGtk as follow,

static void webkit_web_view_init(WebKitWebView* webView)
{
...
 // Attach a new WebKitViewportAttrbutes object given the viewport configuration values.
    GdkScreen* screen = gtk_widget_get_screen(GTK_WIDGET(webView));
    priv->viewportAttributes = adoptPlatformRef(webkit_viewport_attributes_new(980, gdk_screen_get_width(screen), gdk_screen_get_height(screen), webViewGetDPI(webView)));

Therefore, we don't need to call webkit_web_view_init_viewport_attributes on real devices, but DRT still needs  this function to initialize the viewport attributes manually.
