"I'm going to assume this is not a feature since Screen View is new and only serves as a view option at the moment and to replicate it I might have to export it to a certain format though I am uncertain if that's a possibility either. "
That seems a safe assumption. I've not seen this on iPhone or iPad, but on the Mac, I would think that what you describe would require all three layers noted in Viking OS X's post above to contain text and objects in the transparent foreground layer,
to possible contain background objects on and otherwise transparent background layer, and to have a transparent section master layer the width of the pages and the length of that section,
Allowing the background image on the display to appear through all three layers.
iOS devices have the advantage here in that Pages' "pages" generally fill the screen.
Currently not a feature available in the mac OS version(s) of Pages. Might eventually arrive, but I wouldn't bet the farm on it.
