How to vertically center an image inside a picture card?

Configuration Frontend

Hey,
I am using the YAML config from the offical Android TV Remote documentation → YAML Lovelace example

YAML section:

- type: picture
        image: >-
          https://upload.wikimedia.org/wikipedia/commons/thumb/1/11/Amazon_Prime_Video_logo.svg/450px-Amazon_Prime_Video_logo.svg.png
        tap_action:
          action: perform-action
          perform_action: remote.turn_on
          data:
            activity: com.amazon.amazonvideo.livingroom
          target:
            entity_id: remote.living_room_tv
        hold_action:
          action: none

And it looks the same as in the preview of the documentation. However I would like to vertically center the prime video image. In the preview it sticks to the top. Is this possible? (If so, why not add it to the documentation directly? :D)
