This test is not an illuminant test, since is a post over Raw files, and it can drive you really confused, sorry to tell you
Because Arri camera (and mostly all digital) made a debayering in-camera,
RED doesn't: RED is like a film camera, RED records SEPARATELY JUST the three RGB signal, maintain those signals separated, without debayer on board,
and what you see on the monitor is the interpolation that monitor does, not the camera does.
Isn't it really interesting? How to compare these files? Impossible, frankly speaking...
More, the Log3G10 is just a curve that DP works with, combined to Histogram.
Not the final look
Unfortunately many people doesn't know exactly how a RED Cinema Camera works.
The RED sensor hasn't a native iso, and when you modify the ISO on the monitor, you doens't modify the sensor current voltage, varying the sensitivity
Wow, that's all
Arri is a great great sensor, really.
But this test is insignificant applying just a standard lut/grade: we're not talking about Canon C300 mk1 cameras
