Hm, I still want to try out some "university research project" style methods
You should. I would recommend starting here:

QuoteI guess not with my own spectral data, don't have access to any of those instruments.
Most don't have the equipment. It's very specialist.
You can find spectral measurements for several cameras online. There are 5D MkII and MkIII for sure but I don't have the link. It's probably linked in the raw2aces thread (link above).
QuoteWhat is stopping them from releasing this data though? I must be missing something obvious :/ I don't really understand how it would harm their business.
Spectral response should become the standard way of describing a camera's colour in metadata, so software can do whatever conversion methods it wants... I don't see what camera companies have to lose. It would be so great.
Totally agree but..
Competition. Sensor technology is a hot topic and these big corporations don't want to give away anything that may give the competition any insight or advantage that could eat into an already diminishing market share.
The first BMD cameras used off-the-shelf sensors and there is spectral data available for some of those. You could also look at the likes of ON Semiconductor https://www.onsemi.com/support who provide development tools for their sensors. You might find something useful there.
