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

But unless the display actually supports wide colour gamuts that will just make everything look worse.

Here if anyone has questions on the implementation or such.

Is Wide Color preserved when processing video?

Photos only. Apple's APIs only capture in Wide Color when shooting in photo mode, and their documentation only recommends using wide color/Display P3 for images.

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.

Same. Here's the link from the article with the download flag removed: https://www.dropbox.com/s/tgarynpj65ouafd/insta-logo.png

Also changes the profile, I can see the instagram logo here but not on the download

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.

Note that the red test image is only valid for iOS devices, since in Android you can see the Instagram logo even though it doesn't support wide color

On OS X you can adjust your color display profile settings to make it magically appear and disappear.

In wrong color though.

Good to know--I didn't run it through my Pixel. Some devices will do a relative projection from Display P3 to sRGB, which means that it will look "relatively" like it would in Display P3 but projected onto the sRGB color space. Edited to add: and some other ones are doing something even less fancy, which is just to ignore the color profile entirely and just assume sRGB and display it incorrectly, taking for example w…

Since you brought up your Pixel: what is the point of adding something 1% of your customers maybe can see instead fixing that horrible horrible compression that makes uploads from android (80% world wide market share) look like crap?

(Not an android user, I just want to figure out how a company of your size prioritises between bugs and features.)

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.

Can't see the logo on OSX Sierra on my 2014 MacBook Pro Retina 13in.

I have a 2016 MBP w/ touchbar, and depending on which color display profile I select in System Preferences, sometimes I can see it, and other times I can't.

I can't speak for OP but say this does effect 1% of users today, what percentage does it effect in 6 months, or a year? Not bad to be proactive.

And regarding android compression issues, although resources are always finite, I imagine in this case the android team is fairly separate, so they may very well be working on that compression issue while iOS is pushing forward into new terrain.
