Sorry if I missed something and this setting is implemented in Krita. I thought that this might be an interesting topic for the devs (maybe for some future updates):

Already possible with Krita because Krita has a proper color management system part of the core. You just pick a linear color profile, which is by default on the 16bit integer and higher spaces: https://docs.krita.org/Gamma_and_Linear

Cool! For some reason I always had 8 bit selected and since I didn't know what it means, I didn't bother to change Thanks!
