Well like I said before, you can just send Parrot an email. They get back to you pretty quick with the information that you request. You are asking people who bought the drone technical questions expecting them to know how a component of the drone works. If you have a certification to fly at night with the proper equipment, I don't see the harm in experimenting for yourself and reporting your findings.
It's propper to supply a little more detail as to what you are exactly doing or rephrase the the questions because people do want to help so long as there is a clear description as to what is trying to be done. You gave different descriptions of each component in relation to stability. Your post literally says vertical camera and night flying followed by your post, how does it work. Do you mean, "How does the vertical camera work at night to keep the ANAFI drone stable during flight" or do you mean "is the quality of the camera good at night" or "I'm writing a program to control my drone and would like to know how to program a light show since the ANAFI instructions state that the drone should not be operated at night". Again, not being a jerk, just letting you know that your question will go unanswered longer with lack of articulation.
You may know more about this drone than me but your communication skills definitely need a little work. Now that is me being a little bit of a jerk but had to address the condescending tone. Just doesn't make sense to want help but yet be rude when people try to offer it, what is this reddit?
