Yes, but the point is that it's not really that far off. PNG will outperform in screenshots with a lot of empty space, so if you were dealing with that situation, obviously PNG is better. OTOH, QOI still performs relatively well: while the difference is multiples in some cases, to me it seems that those cases are mostly ones where PNG's compression ratio is obscenely good, and therefore QOI is actually still producing reasonably small image files, too. I can see that QOI performs well for what you might use as texture maps for 3D rasterization, for example. Definitely seems to have some applicability to me.
