I don't think that computer has a wide-color display. The 2016 MBP should (at least, the one with the touchbar, not sure about the one without), and the retina iMac supports it as well.
Can see on my 2016 MBP Touchbar 15" w/Sierra
I couldn't either on my MBP late 2013 until I changed the Display Profile to "Display P3". There are other profiles that will show the logo, too, like "Adobe RGB (1998)"
If you change your display profile like this you're going to have incorrect color rendering, so don't forget to change it back after you've had your fun looking at the (inaccurately-rendered) image.
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.
