Hi,

playing around on balena-cloud. I have noticed tha downloads take a long time. It seems delta images are just as big as the complete images resulting in a long download.

running on the device i see

```auto
balena image ls
registry2.balena-cloud.com/v2/224334c4932cacd5341641ab2b6f133c delta-65d81f75713761ac e273a7d1f96d 19 minutes ago 2.87GB

```

balena push fleetname does show small delta images

```

At first I though it is because of development builds. But this also happens with a production variant.

I’m using raspberrypi4 device and it is a new project.

Is this perhaps only a paid feature?
