Digital paintings still shy away from #000000 black in paintings. It still often looks wrong. It'll flatten out just about anything you put it on. The relationships between colours stay the same in RGB as in pigment. It's just that colours mix differently. Adding true black to your real life paintings has this huge possibility of totally blowing up any colours near it if it mixes in by mistake. Digital well... that's up to the artist's self imposed limitations.
That said, all the rules about black disappear once you talk about greyscale images.
As some sister comments point out, while the relationship between colours remain the same in RGB as pigment, the role the relationships and colours play are different from on a website, to print, to a painting.
I also suspect that sub pixel rendering could screw around with off black fonts.
