That *is* true if you view both images at 100%, but that's not how one should look at the issue.
For a given print/display size (which is typically strongly downsampled), the technological level of the sensor has a stronger influence, to the point where the result can be completely in favour of a newer, higher-resolution sensor. The K-1 has very little noise (and it's mostly luminance, chroma noise is barely present, so it doesn't even look too bad), you can push it until ISO 12800 without breaking a sweat. It
smokes the 20 MP 6D in terms of shadow noise.
Don't get me wrong, 24 MP is plenty of them, more than what most people will ever need, but it's not necessarily better. I would be happy with a 24 MP K-1, but that's just because the files would be smaller and the sorry excuse for optimization in Lightroom wouldn't be pushed nearly as much
