No, Xiaomi 14 Pro isn't using LYT900, they are using an 1/1.3" CMOS from Omnivision instead.
Even the current x100 Pro in regards to the camera it even bests iPhone 15 Pro Max for night photos and brightness in video capture, the 15 Pro Max has more vibrant colour from what I've seen. What is needed is the complete package of a phone akin to the OnePlus 12 which is held back by it's camera. This also includes durability and a step up on the software and OS side of things.
