flyctl apps -j : Getting current image and tag information

I deploy an application using --image, which works fine. The web dashboard for the application shows the image name, and the associated tag.

When running flyctl apps list -j, the information about the associated image is not returned (the fields in the json are empty). But if I look at the releases for the specific application, there is information about the exact image that was deployed.
But the original name that was requested (in particular the tag) is not available.

I am trying to build scripts using flyctl and jq, would prefer not having to consume the graphql API myself if at all possible.
