An update to the depot is not an actual update until the devs push it, there’s no changes to the game files. So either way, the answer is no.
A depot is like a way to tell Steam what to download and where to put it. This basically means there’s an update in the pipeline but it’s not out yet. Just to clarify.
I know a while ago the devs went in and removed all traces of Sandman, DreamMaster and Kate. I couldn’t find anything last week when I checked the game files.
