Yes, it is on the same directory of the remote Inselon FS mounted as a cifs mount on a F21 system.
The same command on my local disk (F21 machine, ext4 FS) yields:

I'm still wondering if you do have sparse files; images generally are not.
I don't know but I assume I do. How does one find out if one does.
Only by comparing the byte size (st_size from stat) with the blocks * blocksize
(st_blocks * st_blksize). If the byte size well exceeds the blocks*blksize then
the file is presumably sparse.
But images tend not to be. Sparse files tend to be either disk images (eg
*.img) where not all blocks have been used or data files driven through a hash
table (where data is spread out over a huge filespace in little chunks).
