Correction, was too quick in reading & typing:
The angular problem caused by these microlenses is called 'pixel-
shading', and the result is vignetting, possibly creating additional
noise once corrected (either in-camera or afterwards).

And an even more subjective/false argument:

"Oh, corner isn't sharp, must be caused by projector-lens."
