Here is your confusion, this is incorrect .

Increasing contrast stretches the captured data and will look less flat not more. Darks are darker, lights are lighter.

Try it with 2 picture styles one with no contrast one with max see which 'pops'.

The problem with doing this in camera is it is used to create the jpg, from which the histogram is generated, can cause you to choose a poorer exposure than with a low contrast setting.

Far far better off adding contrast later in post, if it needs it, and if you have space on both ends of the histogram.

Agree about adding in Post.
Correction:
When increasing the contrast setting in camera, the brights and darks get pushed toward the edges of the histogram. Thus the the histogram flattens (distributed more widely) and perceptually to our eyes makes the image 'opens up' and look like it has Less contrast In some localized areas that actually actually flattened rather than compressed.
