The whole "colour science" thing bugs me too, it seems to be the trend phrase among reviewers these days. Never heard anyone use that term a few years back. I shoot RAW only too, and find the same to an extent, the images will end up very similar once I go through my usual motions in processing. But ... I have found that there is a notable difference between manufacturers when it comes to reds, greens and blues. I found I was always having to pull back reds a little with Fuji files, like there was an over saturation, and with my Panasonic I'm finding blues creep in everywhere even with WB adjustment, I often find I'm pulling back blues in the HSL panel, even when there's no blues in the scene
