It's not underexposed, because it's not exposed. The greyscales are artwork, and the brightness levels of each step are what they theoretically should be, to one or less levels. The uncorrected linear greyscale at the bottom shows what should be obvious, that half the steps are below the threshold of visibility, the middle step is just barely visible, and only the brightest 4 steps are readily visible. That's only 4 steps out of 9 that are visible without making levels adjustments which introduce posterisation effects (that's what the middle greyscale illustrates).
