Of course, it is true that the user has no control over how the image hoster usually downgrades the image. But the color test can check if part of the data loss occurs in your browser. (For example, in Firefox and all of its clones the support for ICC4 has to be manually turned on -- cf. Post #6.)
Yes, the Peacekeeper score does vary from one machine to the next but getting through the test without warnings is like testing your browser on many difficult webpages. (For example, the high-scoring browsers here are also the only ones that display my list of difficult webpages correctly.)
So far the posted tests suggest that it is browsers that don't use Chrome's Blink engine are the things that are useless.
