Brightness is also specified for different media — between 100 and 300 nits for SDR content, and 1000 nits for HDR.
Text becomes painful if the contrast is too high, but if you have a cheap screen at 70 nits it won't ever be an issue.
Also, the color calibration AFAIK does not specify brightness. Perhaps the headaches are not from contrast, but from too much brightness?
