Well, sometimes too much info is also not good (as there is too much attention paid to something that is not relevant... just because it is there)
Run my network tests to day & the result is (un)expected
imdisk can mount network based iso just fine... UNLESS share is on ReFS volume
In that case the filesystem of the mounted iso is not recognized by imdisk (and not accessible by the client)
Seems that it is exactly the same behaviour as in previously mentioned OsrVirtualCdAndDisk driver
I also seen an issue with Veeam restore & ReFS share (even they did not want to confirm it, I did not care to pusue it, used personal workaround)
Seems that this filesystem is troubling for other software
