I think the colours pop on an iMac 27" 5k
 

I recall that there was some discussion about the red colours on Dean´s red cars, after he got the S8. At that time I couldn't spot any difference, and kept my mouth shut. As some could clearly see the shade difference.

Well, now I also see the difference. But only on my iMac 27" 5k (late 2015) display. Likely because of it's wider colour gamut :) Best display I have ever owned. Bought it used, just before Christmas

Did I mention that looking at photos of the cars on this forum is an even greater joy? !
