I am disappointed for the fact that a sub-$50M OW is pretty low for a Pixar film but it is not surprising.
Pixar and WDAS use different rendering systems. Hard to deny they look visually far better than say Illumination films. DreamWorks films can look spectacular too but some of their films they've cut costs probably due to the underperformance of a number a films in the last 10 years.
