Overall, the Pro Cinema 4040 is classic Epson "home theater" projector, when it comes to color accuracy and color handling.
Like the UBs, the PC4040 uses a color cinema filter when in its best modes (i.e. Natural, Cinema, Digital Cinema), but not in the brighter modes. This is why some modes on the Epson are over twice as bright as others.
Color performance is virtually identical to the UB series projectors. Even calibrated though, there will be slight differences, not necessarily due to the color itself, but the lower natural native contrast (and contrast differences with the dynamic iris applied too).
In other words it looks/performs like an Epson home theater projector.
I've provided plenty of photos from the PC4040 for your consideration. Please note, I did not have the PC4040 calibrated. I did basic adjustment to contrast and brightness to make optimize them, so that we're not crushing whites or blacks, but that's it. (I also slightly reduce the color saturation for the photo shoot itself (not normal viewing) because my camera tends to slightly oversaturate projected images from projectors. I do that saturation reduction for virtually all reviews. (When I sometimes forget, I warn folks in the review to dial down the saturation on their displays as needed, to make the saturation look correct.)
