What speaks against Tiff as a container? By convention Tiff is already
heavily ICC biased. So best changes to find many readers, which
interprete the ICC profile correctly including the desired TRC.
A different option is to use PPM, the high bit depth version, and
compress and add meta data, ICC Profiles, outside. So it is well useable
inside other containers, say OpenRaster and so simple to implement.
