My overall impression using Siri daily for many years (mainly for controlling smart lights, turning Tv on/off, setting timers/alarms), is that Siri is artificially dumbed down to never respond with an incorrect answer.
When it says “please open iPhone to see the results” - half the time I think it’s capable of responding with something but Apple would rather it not.
I’ve always seen Siri’s limitations as a business decision by Apple rather than a technical feat that couldn’t be solved. (Although maybe it’s something that couldn’t be solved to Apple’s standards)
