[SOLVED] use recent sRGB v2 profile instead of v4/older v2?

FYI: It appears that sRGB v4 has not "taken", and that "the world" still revolves around v2.
TTBOMK, current Photoshop embeds a profile which produces identical results (in 16-bit) to sRGB_IEC61966-2-1_black_scaled.icc (the current v2 tuned for Perceptual rendering intent) when used with Perceptual rendering intent, profile found at the bottom of http://www.color.org/srgbprofiles.xalter. The embedded profile has a name that suggests a close connection with the above profile straight from the ICC.
So does NIP2 (although apparently its profile was not chosen with maximum care).
But not, last I checked, ImageMagick.
Unless there are good reasons not to (and IM being committed to sRGB v4 would be a good reason, because v4 and v2 profiles don't mix perfectly), maybe src/config/sRGB.icc should contain the above?
NNTR (I have not checked carefully exactly what is in IM right now, and again I understand that there may be good reasons not to encourage users to use v2.)

We'll get sRGB_IEC61966-2-1_black_scaled.icc into the Subversion trunk within a day or two. Thanks.

magick pointed out that Debian does not accept the "non-modification" clause of many ICC profiles, including the above.

Also see: https://issues.apache.org/bugzilla/show ... i?id=52704.

If someone knows where to find an sRGB profile acceptable for Debian distribution, please let us know. (If I was less busy I'd try to see if I could create one with something like http://sampleicc.sourceforge.net.)
