For all practical purposes, there's no meaningful difference between a full vacuum and a partial vacuum in this context. For example, the energy stored in the vacuum is nearly the same, so in case of explosive decompression, the partial vacuum will do 99% as much damage as a full vacuum. In other words, the misconception is yours.
