A few years ago you would have been right. As referenced in the article, Apple seems to favor boosted blues: "Apple's algorithms for the sky are designed to boost the color, trending towards a blue, cool tone during the day that's highly recognizable compared to the Galaxy S21 Ultra. The iPhone 12 Pro Max photos are more vibrant, while the S21 Ultra has a flatter color profile. Neither is quite true to life, with the real color somewhere in the middle."
It's like somewhere along the way both companies decided to do a 180 with their color science. Samsung used to favor vibrancy and Apple used to have flatter color profile. Anecdotally, people seem to prefer the vibrancy. MKBHD's blind photo test has always been won by the more vibrant photo snapper.
I also picked A for most photos 'cept the night shots. They are more colorful.
