@Paul Grimwood Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Downloading to a null-type destination (e.g. /dev/null on Unix-based systems; NUL on Windows) with --check-md5 will achieve the desired effect re: validation.
We have work upcoming in the eventual future (no timeline yet) to be able to thoroughly validate a blob on upload; but that is a ways out.
Please let us know if you have any further queries. I’m happy to assist you further.
