I can’t speak for the a320 but all the types I’ve flown the actions for a flameout are the same as for severe damage without fire, the only difference is that for the latter you are doing them at 400’ as memory actions and for the former it is once you’ve cleaned up as an NNC. (Presumably in the a320 ECAM gives you the smae actions either way, I dunni, not rated on it),
thus the only functional difference is whether we are doing the actions urgently from memory or not.
Ambling back into the cabin for a look in slow time is a de facto decision to not treat it as severe damage requiring an immediate secure.
