In a packet capture from an upstream switch port mirror, you would see the VLAN assignment. The port mirror captures the traffic as it is on the network, including any VLAN tags. GRE or IPsec tunnels encapsulate the original packet, including VLAN tags, but the VLAN information is not visible within the encapsulation headers.
