POE upgrade for rb951Ui-2HnD?

I have done several poe upgrades of Omnitiks and 750UI’s etc. but this one seems to be different.
Or is it because it is running v.64 and already has latest poe firmware?

But I still can’t see the power output, voltage, amps etc. on the ether5 port (The only poe-out.)

Any ideas?

Is too new. No winbox settings was added.
