Canon!Dumbledore didn’t sacrifice himself to save Harry (and Draco) -- he was already dying, and he just arranged his death in such a way that Snape would be in the most trusted position possible, and the Elder Wand permanently deprived of a “true master”.
He failed in the latter goal.
But he was already dying because of anti-Voldemort choices he made. I’m not sure we can expect MoR!Dumbledore to make the same choices unless he sees them as a fitting end for his life (which he may not, given that he’s not Harry’s mentor figure).
