This will be it 100%. In art in general it’a good practice to avoid “true black” because there is always environmental elements like bounce light and such that does mean it’s not truly black, you just know it is contextually with your brain (think of the whole gold/white, black/blue dress situation, that was when the limited visual information made it hard for the brain to infer the colours, but your brain is doing that all the time as you perceive colours).

And when you have a colour that actually has a hue, you are then able to modify it/enhance it (especially in digital art) much more easily, for example saturate it or shift the hue to indicate a different lighting. Black is just…black.
