I haven't seen digital Imax. But if it was using two projectors, like it should do, the blank space between pixels (the "screen door") would be filled with light coming from the other projector, as the two screen doors are not going to align perfectly.
I'm guessing that's one of the main points of using two projectors. Hide the screen door.
It would still be noticeable sitting in the front rows on large areas of solid white color, as the light intensity, of even the "double" screen door, would leave some darker thin lines. But much less than if they were using a single projector, as virtually zero light would reach the inter-pixel areas in that case.
With two projectors ever so slightly offset, the screen door effect would be reduced to roughly half by severely reducing the contrast between the black lines and the adjacent pixels using the light from the second projector to fill the empty space.
