I haven't seen it documented anywhere, but to be honest I just assumed that the threat generated was based on the amount of attack power reduction, thus meaning that increased reduction equals increased threat. That being said, I would love to skip the talent, so if anyone actually has any evidence either way - please share :-)
Update: The only info I've been able to find on this is here: https://github.com/magey/classic-war...ved-demo-shout - concludes that improved demo shout does NOT increase threat generation.
