Does “Color Science” even matter?

I bought a pair Sony A9 for all their technical capability when I made a career change into full time photography.

I fought it's raw colour output for years creating preset after preset, until I found a third party colour profile which helped, but not long after..

..I bought a pair of Sony A1's and except for a colour inconsistency between 70-200 & 24-70, I am happy.

But the first time I loaded up a Hasselblad X1D raw portrait, I was amazed by the colour presented to me, so much so it made it difficult to know where to start processing because I felt like I can only make it worse. I've since had X1D II, 907X and the X2D - just love the raw.

And now, even if I'm going to change colours considerably, I still prefer having a great base to work from.

But if we are talking about raw files, you are still talking about the difference in the raw software, not the camera/sensor. It's possible there are some subtle differences in the CFA on different sensors (that special Phase One camera for example where they concentrated on tweaking the CFA dyes) but mostly the colour is determined by the raw software. As some people have said, you don't have to use the canned camera profiles, you can make your own custom profiles and tweak the colours to be anything you want.
