Well, it’s already easy to make a visually convincing fake photo if you’re motivated to do so. For this picture, some local models do make more convincing text, but if the angle and stylization are still too much, you could also just remove the tell entirely by asking for the napkin to be removed, replaced with another object, or changed to a flat color, floral design, etc. Tells only still exist at the point because the prompter either doesn’t care or doesn’t know.
