Well
There are precise values in attitude, both in rate and deflection, that trigger a definition of "Jet Upset".
It is arguable 447 was beyond those values almost immediately post Auto Pilot drop. Seconds after loss of AP came the first Stall Warn from the aircraft. One assumes an aircraft alerting an aerodynamic Stall is beyond Upset, and closing in on Loss of Control (Stall, By Definition).
Perspective.
