I don't get it. Is it saying Olo is an example of a color that can't be displayed on modern RGB displays?
I wonder if someone could sell pieces of paper which have this color?

What's going on here is different. The researchers managed to identify individual cones in the retinas of human subjects. They then shot tiny pulses of light at ONLY the M (green-sensitive) cones. This avoided stimulating the other cones, and subjects saw a color they could not have seen otherwise.
The issue here is that the S, M, and L cones have overlapping sensitivity curves: normally if you shine green light on the retina, all three cones will respond, and your brain will say "green". But here they are stimulating only one cone, not all 3.
