We can only view it from where we are in spacetime , and thus all the date we have on it is from our own reference frame. Any predictions about its fate are based on OUR viewpoint, not that of a point many light years away.

There is literally no way for us to know if it has "already" gone supernova. That reality has not reached us yet, and is therefore nonsensical to talk about.
