Imgur seems to be changing the profile or somesuch because I can see the logo when I downloaded the image but not on the imgur image here.

    Really strange! I get the same behavior. I thought it was maybe Chrome vs my image viewer, but if I open the downloaded image with Chrome, it's just pure red, but the preview in Dropbox I definitely (faintly) see the logo. If I right click and save the dropbox preview, I get a 14kb image, but the downloaded image is 29kb. As far as I can tell they're both PNGs with the same bit depth.

  Interesting! From this link, I also see the logo on my rMBP (in Chrome or Safari) – but not in the IMGUR link I posted above, even though the IMGUR link reveals the logo on an iPhone7 iOS/10 MobileSafari. Changing Chrome/OSX to report its User-Agent as iOS9 MobileSafari does not help get a different image from IMGUR.

  This is interesting. Shows up in Firefox here, but not in Windows built in Picture viewer. My display is certainly only sRGB so I guess Firefox is doing some kind of correction.

    I've written lots of graphics and image processing code. You can see the logo because almost every computer system on the planet handles color spaces incorrectly. Apple's devices are actually better than most, though third party drivers such as those for printers can sabotage their color handling. The canary image will appear as red without a logo on a computer with an sRGB display if that computer correctly handles color spaces throughout the whole imagine pipeline. That's a lot of ifs. If your system ignores color spaces, you will see the logo because the Display P3 (DP3) color space gets compressed into sRGB. When you look at real world DP3 images on this system, you will see the reds as being more muted. The same thing happens if you use an Adobe RGB camera (there are lots of these) and display it in sRGB, except with the green channel, because AdobeRGB has a wider green range. No matter which color space you use, an image will contain RGB tuples. The color space is additional meta-info which says how to interpret those tuples. Lots of software will ignore the metadata and simply assume the RGB tuples are used in the same way as it expects.

      So... correct me if I'm wrong, but this DP3 color space they're using isn't increasing the bit-ness of the color, it's still 8 bit color, they're just using a different color space to get a wider range of color with less precision? Seems sort of silly to me as most designers will be on sRGB displays and most people will be used to how images look in the sRGB space, but I guess it's one more way for Apple to sell more new Apple stuff by pretending these extremes in color are more important than precision in other parts of the spectrum. I can definitely understand going to 10-bit color, this, not so much.

        They're not mutually exclusive. Right now basically every single display is 8bpp even if Apple went to 16bpp displays when using normal applications most people wouldn't see anything special because the source data is all still based on eight bits per pixel. By improving the color gamut you can actually see a difference on the display. Areas where there were differences and color before but it was invisible because of the display now showing actual difference. It's slight, but it's there. Seems like a good move to me. I imagine moving to 10 or 12 bit color will be the next step.
