When the corners were not in line, your eyes would instinctively be drawn to the distortion.
Some images or videos will tend to highlight the distortion.

You are talking about a much larger screen though, and multiple projection sources.

The smaller (lol.. small.. 80--100") curved screens I've seen are not curved all that dramatically, I imagine there is still some calibration/compensation to be done on the projector.
