Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.

Kuo: New 31.6" Apple Display in 2019 and 15-17" MacBook in 2021 to Feature Mini-LED Backlights [Updated]
An excerpt from Kuo's research note, obtained by MacRumors:
We believe that mini LED, compared to OLED, will be a more suitable solution to offer wide-color gamut (WCG)/high-contrast/high dynamic range (HDR)/local dimming features because of its longer life and no burn-in issues for Apple's medium- and large-size products targeting at productivity positions.Kuo believes that the 31.6-inch display "will target a very high-end position" and feature an "all-new design."
We forecast that Apple will respectively launch an all-new design 31.6-inch monitor, a 10–12 inch iPad and a 15–17 inch MacBook equipped with a mini LED backlight unit (BLU) in 2–3Q19, 4Q20–1Q21 and 1–2Q21.
In a previous research note, Kuo predicted that Apple would launch both a 31.6-inch display and a 16-16.5" MacBook Pro in 2019, so it's not entirely clear if the 15-17" MacBook refers to a separate notebook or if Kuo now believes the 16-16.5" MacBook Pro is coming a few years later than he originally expected.
