Sorry everybody for these late replies. I was busy at work.
The Chrome version is the same in all the samples, because Chrome refuses to use anything but an sRGB profile. Well, to be more precise, and as it has been said, Chrome use my custom primaries if I have set a system custom profile, but with a hardcoded TRC, that happens to be the same as in an sRGB profile. As my custom profile is not that different to an sRGB profile, Chrome renders the image mostly the same no matter the profile I use.
And yes, the RT rendering was my color managed intended rendering. And it showed like that in Firefox (my main browser), so I take for granted everybody would see it that way. Wrong! Anybody looking at my processing on a Chrome browser will see an image that :
So what do I do now? Edit my images with overcorrected shadows (in fact, overcorrected global luminance) so more than half the viewers will see it as intended (because they use Chrome)? Or do I keep processing images for myself in the believing that someone that happens to have a color managed system and curious enough will load my .pp3 to see what I’ve really done (even it’s more than likely that he/she will be browsing the web with Chrome and will be looking at a dark, unpleasant image?
Those are the questions I’m trying to find an answer to.
