You're correct. It struggles in outdoor situations, particularly overcast/low-ish light and high-glare. It seems to want to overcorrect. You either get a shot that's too dark and need to adjust afterward, or you end up with amped-up blues/greens. By comparison, my previous generations-old Samsung Galaxy in HDR mode was an incredible phone camera. Spot-on color profile and excellent contrast in comparable conditions.
All of this said, the sky conditions were in fact weird for that shot above. There was a light hazy overcast with some diffuse darker clouds floating in front.
