Hi Ivan,
You can use the following EVPL configuration which would allow you to see the mac addresses e.g. in the following example you can see the mac addresses under bridge-domain 10.

interface GigabitEthernet0/1
 switchport trunk allowed vlan none
 switchport mode trunk
 service instance 10 ethernet
  encapsulation dot1q 100
  rewrite ingress tag pop 1 symmetric
  bridge-domain 10
interface Vlan10
 no ip address
 xconnect 10 encapsulation mpls

Yes, as far as I understand there is no mac learning which is great for resource utilisation and scalability.  No requirement other than "it is helpful for troubleshooting" to see any macs.
