Reactivity of Video Doorbell Dual notifications and deactivation of LEDs!

Hello.

I bought the Video Doorbell 2K (Battery-Powered) 6 months ago.
I learned that a new model Video Doorbell Dual (2K, Battery-Powered) is released.
I am interested in buying it, but before and after some research, I have 2 questions:

-Is this new model responsive with notifications? I have read several times that the notifications come much later than the first doorbell model I own.
I would like to have your opinion please?
The responsiveness of a doorbell being essential…

-Is it possible to deactivate all the LEDs on this new model, including the LEDs of the 2nd camera?
Which is an important criterion for me for discretion outside my apartment as soon as a person passes by, and to save battery too.

Thank you.
