Perhaps sensor heat "stimulates" all 4 pixels - but red predominantly, so we get that dirty brown/brick-red noise?
I'm keen to try out the darks on DSLR Ha images - that's where the strength lies for me as it takes stacks of 15 minute subs to get decent results for me, so the ICNR route was very time consuming to produce images like this...

I think that took about 3-4 nights of imaging!!
