Having watched both. Yes the Incredibles are much much worse. Especially if we focus on the color palette. You could have not picked a worse example.
But for example Moana is not worse than Cinderella. Arguably it's better. But the algorithmic choices around perspectives, reflections, etc. Were not really automated. In both cases a lot of people where involved in each scene, and I am confident, they went over every frame, checking the result was what they wanted.
Additionally, hand-coloring wasn't necessarily a more pure creative choice anyway. It was dictated by material conditions such as the availability of pigments, studio constraints, time pressures, etc.
This feels like an incredibly disingenuous comparison and I suspect you know that. But just to play along, real artists had to design the character models, real filmmakers had to decide which shots to capture, real editors had to put that together to make a cohesive story. Also they almost certainly went through color grading after having completed the rendering, so the colors are certainly selected by humans to produce a nice looking composition.
Is Pixar Incredibles where a computer algorithm made decisions about exact colors worse than Disney Cinderella where it was hand-drawn animation?
