I think the ProPhoto RGB is to big for current colorspaces of mobile
devices. We want to improve the rendering intent 0 (perceptual) like the
PRMG (Perceptual Reference Medium gamut) does it in printing.

This all is a seminar for us students and maybe there are lots of
solutions, but we also try to learn something, for example how you can
create a workingspace.

In our different projects in our study we developed for example a tool
with a GUI for profiling displays and cameras in particular of mobile
devices.
We also know, that colormanagemente isn’t supported yet on iOS and
Android, if any only on application level.

I'm just a student interested in this topic and trying to learn in a
practical way.

So thanks all for your help.
