Description

It would be rather nice, if Darktable would recognize JPEGs in the AdobeRGB colorspace and automatically switch to our embedded AdobeRGB profile in the colorin iop.

These seem to be the relevant changes I see when I compare an sRGB JPEG and a AdobeRGB JPEG generated by my camera:

-Exif.Photo.ColorSpace Short 1 sRGB
+Exif.Photo.ColorSpace Short 1 Uncalibrated

+Exif.Image.WhitePoint Rational 2 313/1000 329/1000
+Exif.Image.PrimaryChromaticities Rational 6 64/100 33/100 21/100 71/100 15/100 6/100
+Exif.Image.YCbCrCoefficients Rational 3 299/1000 587/1000 114/1000

-Exif.Iop.InteroperabilityIndex Ascii 4 R98
+Exif.Iop.InteroperabilityIndex Ascii 4 R03
