It a "gaming" thing that improves visibility by lowering blacks.
"It aims to brighten dark areas of the game world without overexposing the brighter areas, so that gamers can more easily spot enemies in darker areas of the map without having to turn their brightness up so that they essentially get blinded by ingame light sources." prosettings.net/library/what-is-blackequalizer/
If all you want is to darker blacks, you can use levels to lower the black point which would make the blacks darker. You could also use another shader (such as fake HDR) to achieve higher contrast (which would would darken the blacks).
EDIT: It seems I misread what you asked, I thought you were asking about darker blacks, not lighter blacks. You should still be able to get that effect using levels, and just raising the black levels.
