IMAX does not send the exact same image to each projector, they are slightly different, together they merge.

IMAX digital is 2K, it is not 4K. IMAX does their own DCP's and they distribute themselves, their DCP's are 2K.

Depends, IMAX digital has more light. Remember, you cannot compare 4K to IMAX 3D...there is no such thing a 4K 3D for digital cinema at the present time. 3D is always 2K. There a lot of factors that come into play, just because it is 4K does not always mean superior.
