According to http://www.color.org/v4spec.xalter "Most platforms and color management applications have now migrated to ICC V4, or are in the process of doing so."

 

Viewing the pdf version of the test page at http://www.color.org/version4pdf.pdf in Safari (v.9.0.3) or Preview.app (v8.1) suggests that OS X does support ICC v4. However, after using Safari's "Save as" function to download the pdf & opening that in AP, the large image looks identical to the third image in the "Expected results" section, captioned "The system does not support these ICC profiles."

 

I'm not sure how to interpret this. I would expect the results to at least match the second result, indicating AP supports version 2 profiles.

 

Have I misinterpreted how to use the test pdf, or is there something else I am missing about this?

Hi R C-R,

 

I have had a look at this and for some reason in Safari it is change the top right quadrant into a blurred imager rather than a green square but when viewed in Chrome the green square as the second result.

I get the same blur as you do with Safari (& Preview) & the same green square with Chrome -- the Chrome image looks identical to the second smaller image, indicating (I guess?) that Chrome supports version 2 profiles.

 

However, my main concern is why, when the downloaded pdf file version of the page is opened in Affinity Photo or Designer, it looks identical to the third smaller image, which seems to be saying neither app supports ICC V2, or at least not the two v2 profiles used.
