Urgh, all the files are identical. This can happen for two reasons:

* nouveau is caching the edid, and not fetching it from the hardware
when GCM requests
* the monitor is sending the same edid for all selectable modes
* the monitor is set to not update the edid (my HP calls this DDC/CI
Auto EDID Update)

Can you ensure the Auto EDID update feature is turned on, and if not
could you try:

1. shutdown
2. select adobe on the monitor OSD
3. startup
4. dump edid
5. shutdown

Then repeat with the srgb mode to see if nouveau is indeed caching these.

Ideally we can detect common modes using their primaries and just
append something like ("Abobe RGB") to the profile title and filename.
