This ReShade preset is only a LUT edit, hence zero performance impact.
Install ReShade. There will be two packages checkboxed by default. Leave those as they are. When a big list of shaders appears, select "uncheck all" and hit "next".
Download the edited lut.png from here and overwrite the blank lut.png with it.
Path
C:\Program Files (x86)\Steam\steamapps\common\DARK SOULS REMASTERED\reshade-shaders\Textures
Bring up the ReShade UI in game and checkbox "LUT".
Adjust the Chroma and Luma sliders to your preference.
(Screenshots taken with in-game brightness set to 3.)
Cheers
