The roadmap specifies 24 different formats for sRGB images and 24
additional formats for non-sRGB images.
Presumably the 24 additional formats for non-sRGB images allow GEGL to
request, as needed, a conversion of the RGB data from being encoded
using sRGB primaries to being encoded using "User_RGB" primaries and
Given the 24 additional formats for non-sRGB images, it seems pretty
important to be able to detect when the user opens an sRGB image and
when the user opens an image that's in some other RGB working space.
So again, upon opening an image, how do you plan to detect whether the
image is an sRGB image or not?
Will you compare MD5 checksums?
Will you consult the profile descriptions?
Will you examine the profile colorants and TRCs?
If you don't understand the context of the question, see the following
article: Will the Real sRGB Profile Please Stand Up?
It should be noted that the article doesn't list *all* sRGB profile
variants (new ones are being made every day). In particular, the article
doesn't list sRGB profile variants distributed with Canon, Nikon, etc
