When you are Bccd there is never any access to the Bcc list - that's the point of it (so that for example you can run a mailing list without everyone seeing everyone else's addresses) - so you won't see anthing of this sort other than your address showing up in the long header (command-shift-H to view), e.g.:

(XXXX is one of my aliases). 'email@example.com' is the actual From address as opposed to the Reply-To address.
I am using the icloud web client not an actual application so command-shift-H to view will not work, in most email clients (web or otherwise) however it will tell you that you have been bcc'd while not showing you other people in the list. I think your first comment was right tho and there is no issue it would just help if apple showed you that you had been bcc'd in the web client.
