Right, so while recorded references, information, gear settings etc online will get you in the direction/path of what you’re looking for…
Ultimately you have to judge yourself in the room with your gear because it’s the same way you heard your reference!
It’s not really fair to compare it to a “recording of a sound (mic’d cab and or room through whatever medium you listened with) because of physics
there are tricks of course to make a mic’d cab sound like in the room sound but your skills/knowledge can only take you so far (see linked video)
If you want a amp/cab in the room sound, just get a cabinet and P.A with your modeller of choice.
Or if you have studio monitors maybe try this trick as someone already said but in video format
It’s similar concept to the smoothing parameter you like but much more versatile and powerful!

EDIT: I see you’re already doing the trick but I’ll just leave this message here
