Open Draw. Define a graphic style that uses theme colors for fill and stroke. Assign the style to a shape. Save the document. Examine the file markup. The defined style has correctly loext:stroke-complex-color and loext:fill-complex-color. But the loext:theme element is missing. Draw should be treated same as Impress. Thus I expect the loext:theme element as child element of a style:master-page element.
