I agree, it seems that there are pretty consistent biases, so I have the answer to my original question, thank you all!
One thing I'm wondering though is why is there a difference across channels? Because electronically, they should be the same, just with different filters on top, right? But then again comparing histograms there are clearly differences in which values which channel have lots of or none of. I guess I'll do some tests to figure this out, comparing different regions.
