Comment (by pdr0):

 You're right about APP14, and it is YCCK

 ISO/IEC 10918-6:2013 (E), section 6.1:
   ColorTransform    = 2 [YCCK]

 See post nine

 Why are the photo CD PhotoYCC equations on wikipedia
 https://en.wikipedia.org/wiki/Photo_CD#Encoding

 different than intel's PhotoYCC Color Model equations ?
