Which Hitler death is cannon

So there’s a Hitler assassination mission in every sniper elite game since 2. I’m wondering if these are cannon, but if so, that only means one can be cannon. Obviously there was only one Hitler, we can assume that hitler doesn’t have multiple identical twins which Carl is killing off one by one in each game. Therefore these missions can either not be cannon, or one of which could be cannon. What are your guy’s thoughts on this? Do we have any game evidence to suggest one being more plausibly cannon than the others? Either way, please share your thoughts.
