The truth, as always, is somewhere between "true" and "false". I.e., "it depends". While z/VM can establish a virtual "box" that has the same dimensions without regard to the underlying hardware, the color and texture of the inside of the box will tend to follow that of the real hardware. Under certain lighting conditions the differences are very apparent. Under others, not so much. It really depends on whether the guest needs a particular shade of blue. (Just trying to avoid the obligatory car or sports analogy.)
