Don't put a lot of faith into such dE reports, there are a number of reasons it's just a feel good option. IF the dE values were really large, you'd see this on-screen anyway.
I'm sure you're right. I will say though that just eyeballing that Cinema, I could tell it was pretty wonky. Anything with subtle middle grey tones looked awful. After calibration, it looks pretty good.
I have one of those Dell Ultrasharps on another system, and prints match that thing terrifically well now, which is really all that matters to me.
Of course, I want an Eizo, but that will have to wait until I've sold quite a few more prints.
