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.

Blurry Leaked Images Depict Alleged 'Apple OLED TV' in Testing Facility [Updated]
A Google translation reveals that the original Weibo post refers to the pictures as "Apple OLED TV spy photos", and claims that the display is "about 60 inches" with a narrow frame design and a metal shell.
The first two photos show a closed-circuit TV screen outputting front and rear camera angles of the alleged Apple television mounted on a rotating test bed in the center of an acoustically insulated room, with connecting cables running down a table into the floor. While the original Weibo post notes that two black spots at the bottom of the screen depict a camera, these aren't visible in the photos.
A third image appears to be taken from the door shown in the previous two images, while a fourth photo, below, shows what looks like the same display from a different angle, connected by orange cables to large unidentified testing equipment.
It's virtually impossible to say anything definitive about the contents of the photos, and Apple is known to regularly test devices most of which never see the light of day as consumer products.
As far as Apple-branded television rumors go, these had been circulating for years before a Wall Street Journal report two years ago essentially confirmed that Apple had shelved its TV set plans back in 2014. The company reportedly spent more than a decade researching the possibility of releasing an ultra high-definition television set before deciding to cancel the project because it couldn't find untapped features that would give it an edge in the television market.
Apple is rumored to be working on a fifth-generation Apple TV box that's able to stream ultra high-definition 4K video and it may well launch this year, so whether or not this could see Cupertino revive its plans for an accompanying or integrated television set remains to be seen.
Discounting the "60 inches" reference in the Weibo post, this leaves the possibility of an Apple-branded external computer monitor. Apple discontinued its nearly five-year-old Thunderbolt Display in 2016, but the company is said to be working on a "pro" display to accompany a future Mac Pro machine due next year. 4K and 5K LG Displays are already available from Apple, but these don't fit with Apple's usual aesthetic and have been prone to issues.
Whatever the origin of these photos, it's best to take them with a grain of salt, for now at least.
Update: Less blurry versions of the images were posted to our forums earlier this week, with multiple related forum accounts suspiciously created to discuss the photos before the discussion thread was deleted. Forum member brock2621 also found some suspicious artifacts in the images.
