I can’t, as then I’d have to re-calibrate it again. But you can easily just increase the contrast setting on your monitor and leave sensible defaults for the rest of us :)
And that’s why I replace all the panels on my laptops with proper ones, and only use monitors with good contrast ratios.
As low-budget option I can recommend the Fujitsu Siemens P17-2, it’s from 2004, available used around 20 € and has better contrast, brightness, and viewing angles than any TN panel even today.
It’s ridiculous that a monitor from 2004 is still better than anything the complainers in this thread are using today.
