To the best of my knowledge, all profiles included in the "Elle Stone's Well behaved Profiles" pack are free from known copyright restrictions. I am not a lawyer.
All nominally "Gamma=2.2" profiles have a gamma=2.19921875 TRC, in keeping with the gamma value used in nominally "gamma=2.2" V2 profiles. This gamma value reflects hexadecimal rounding that was unavoidable in V2 profiles.
All nominally "Gamma=1.8" profiles have a gamma=1.80078125 TRC, in keeping with the gamma value used in nominally "gamma=1.8" V2 profiles. This gamma value reflects hexadecimal rounding that was unavoidable in V2 profiles.
All the RGB and Gray profiles are provided in V2 and V4 versions, using their "normal" tone reproduction curve, plus variants with the sRGB TRC and the linear gamma TRC.
