Hard agree. As a new parent, I bought a modern mirrorless camera before my kid was born, and the difference is noticeable. Especially, as you say, around skin details like milia (white spots on a newborn's skin) which often get wiped out on my Pixel (I'm sure by the AI processing).

If you are considering an expensive phone upgrade based off of the camera alone, consider buying a dedicated camera first, I say. I know the best camera is the one you have on you, etc...
