It's possible for a write to fail both with a write error and a write concern error - for example if there is a duplicate key violation during an insert, we will still need to wait for write concern to ensure that the state that triggered the dup key error is visible across the majority of nodes. The shell bulk api, however, swallows write concern errors when doing an ordered bulk write if it encounters a write error. Unordered bulk writes correctly report both the write concern error and the write error.
