I'm using a custom display preset to reduce apple's default gamma boost as the default profile has it way too high in my opinion (even with contrast set to normal in accesibility settings) and dark images become impossible to decipher due to black crush. I think Apple may even have a gamma lock on the default preset/color profile to force images to be darker then they were actually intended to be.

The best solution I've found is to duplicate the default display preset, tick "Apply Apple Gamma Boost" and set it to 1.1, or adjust it to your taste (I think min is 1.0, max is 1.5). You can also set a custom white point and lower the x and y values to make the display color cooler, as the default D65 is too yellow in my opinon.
However you have to choose a constant SDR brightness/luminosity for the preset, and the keyboard brightness controls get locked.
Using an app like gamma dimmer to control the brightness on locked presets is probably the best solution but does anyone have a better workaround to unlock the default system brightness?
