Yeah, I also like being able to get real blacks, and certain kinds of panels can do it (I'm not an expert on panels by any means but I think this is one of the bigger selling points of the OLED family of panel designs is that they can turn off a pixel completely, which let's them get an infinite contrast ratio and therefore pure blacks).

But on a lot of displays (including a couple of the ones I use all the time) the panel can't really do it well, and so there are all kinds of hinting and cheats and other workarounds, and so to get perceptual black, you actually wind up cranking the lum up a little, and that's what I've tried to do with the baseline Ono-Sendai Hypermodern blacks, is give a range of options starting from absolute black, and going up incrementally to GitHub "black"/darkest which is a very expertly designed grayscale (their designers on this are world class), but it's light, it's really high to cope with just about any panel.

If you want to try it out, you can pop these codes into whatever way you set colors:

The "Ono-Sendai Memphis" grayscale starts at #000000.
