No. XPS is EXTRUDED (one big mass squeezed through a die), so there's no bead structure — it's homogeneous. Cut surface is smooth + uniform. That's why architectural models, theatre props, signage backers usually use XPS even though it costs more.
EPS is EXPANDED — small beads of polystyrene blown up with pentane, then fused together. The fusion lines remain visible as a slightly raised hexagonal pattern on cut surfaces. Look closely at any cheap packaging foam to see it.
