Isn't one of the main uses of JS to get the contents of elements on the page? That "97%" and "100%" would be clearly evident.
Though I suppose rendering differences that affect z-order or visibility could be detected indirectly, by listening for pointer events on elements that are "supposed to be" visible/hidden.
