Correction: No. Monochromatic only means you use one color. Black can always be represented as it is 0% of that color, regardless of which. Even if you have monochromatic red light, you can show/see every shade from pitch black to full monochromatic red, an unlimited amount of shades using monochromatic light. To refer to white as monochromatic is somewhat strange as it uses all possible colors but I would definitively say a zebra is more monochromatic than bichromatic.

Correction: Here we have the classic square and rectangle definitional situation. All black and white is monochromatic, but not all monochromatic is black and white.

Correction: Color theory does not take light spectrum science into account, at least not basic color theory like this. Zebras are achromatic, defined by its use of tints and shades, i.e. black and white, and absence of color.
