When I see the photos that some people find under-saturated or lacking in contrast from the Pixels, I wonder if the photos are actually the more accurate ones. Kinda like how most people will tend to like bigger bass and louder treble on their phones while audiophile would go for a flatter or mid-centric sound.
These photos for example from DXOMark:

To me the iPhone image pops out more but the Pixel's image is closer to what I would expect how things would look in the real world.
For me, I would prefer a more accurate color representation rather than an over-saturated one. Should I find the need to make a photo pop, I can always do it later with some very basic editing. Making a photo pop more is easier than correcting inaccurate color reproduction.
