If you have a Macbook and can't see the logo on the canary image, try changing the color profile for your display. On my mid-2014 rMBP, the default color profile was "Color LCD", but I could change it to "Display P3" and see the logo.
To make the change: System Preferences -> Displays -> Color
Thanks for the hint. On my 2015 Retina MBP, when opening the IG image in Preview, I see the IG logo. However, when dragging the image into Chrome, I do not see it.
