When handling sparse stream, a thread is executed. This thread runs a read() or write() loop (depending what API is called; in this case it's virStorageVolDownload() and this the thread run read() loop). The read() is handled in virFDStreamThreadDoRead() which is then data/hole section aware, meaning it uses virFileInData() to detect data and hole sections and sends TYPE_DATA or TYPE_HOLE virStream messages accordingly. However, virFileInData() does not work with block devices. Simply because block devices don't have data and hole sections. What we can do though, is to mimic being always in a DATA section.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
