Hello,

what is the size of your created nvme/vm-100-disk-0 image? Have you enabled thin-provisioning?
Can you add some screenshots from the GUI with the different sizes?

thin-provisioning disabled. Can it be enabled if machines are created on the disk?

The difference from 920GiB to 899GiB is the zfs filesystem offset.
The 7.96GiB are the real used data on your storage and the 825GiB you have allocated to a VM.

You have to enable thin-provisioning but I don't now if it will work with existing volumes.
