It's no quirk of screen, browser, or anything else. It's a matter of characteristic...it's not the amount, it's how the noise presents. I'll produce some direct comparison images and GIFs from DPR data so people can judge on their own screens. Canon sensors are still more blotchy in most instances. Even the a6000 has a better noise characteristic than most Canon crops, with the exception of the reds and brown/tan swatches. It does have more color noise, however it's cleaner, random color noise with more per-pixel frequency and characteristic...it's not blotched.
I use that term very explicitly and specifically...blotched. That refers to characteristic, not amount. Canon color noise has a nasty characteristic. It's one of the things hate bout the 5D III at low ISO...it's the same blotchy characteristic in the shadows. Noise character matters just as much as noise amounts. As far as amounts go, there isn't a full stop difference between any one of the APS-C cameras. At most, on a normalized basis, there may be a third stop difference, but that's to be expected...barring color noise characteristic, the amount of noise overall is ultimately determined by total sensor area, Q.E., and maybe fill factor.
Jrista, could you please post a few examples of "good noise" and "nasty noise"? I am not sure I can tell one from the other.
