Lens contrast vs. adding contrast in post

Lens reviews often talk about sharpness and contrast, with more of both being better. I understand why you can't make up for a soft lens by sharpening in post, but why can't you fix a lack of contrast in post? In Lightroom, sliders like clarity and texture seem to do a good job at adding microcontrast. My guess is that lens contrast has to do with the ability to distinguish between extremely close colors and register them differently on the sensor (I know I am articulating this very poorly--forgive my ignorance). If the sensor registers two pixels as exactly the same color, increasing contrast through any of the numerous ways in LR won't do anything. Is that right? I would love a good explanation for this.
