However the developers responsible for XV did say that they would be open to working with someone who could help then do this a better way. So if anyone here is able to provide patches or to assist the XV developers with this issue it it might be possible to get this corrected at some point.

It seemed to me that the biggest issue is that the underlying
hardware is setup with controls such as "contrast", "brightness"
and "gamma" all with undocumented effects and ranges, rather than
being able to set an arbitrary curve shape. This makes trying to
set a calibration very awkward and imprecise.
