It's a very misunderstood rgb value.
We have rgb 0, which is almost completely black on something like Oled.
But not always.
RGB 1 is very very dark, somewhere between 0.001 nit and 0.01 nit.
Effectively, because of the forward voltage of a pixel, these values are not achievable @ single pixel levels.
If you even wanted a "whole patch" of 0.00x, you need dithering. Dithering lights up a whole patch of pixels surrounding the target that you actually want alight.
This is even harder when the panel gets bigger, because you have not only longer electrical connections, you have way more variability in the deposition when the panel is made.
But RGB 111 is mythical, because it is in between RGB 000 and RGB 222.
You often have to Crush 111, because without doing that, you can not produce consistently a dithered value < 0.1nits.
That is to say, don't be afraid of crushing 111. It's fine, you'll never see it, but everything between 222 and 555 could look much better.
This is especially true on these new oled laptops, which have very poor near black performance. These laptop panels basically look like they have IPS glow on content that use softblack, think dreamy noir scenes, which are quite common.
Point is, Oled on Laptops is alot of hype, it's better than IPS, absolutely, but it's not at the Lvl of TVs with much better near black handling.
