Rick, it's not a good idea to apply ASI294 (IMX294) calibration tricks towards the ASI1600, they are totally different in relation to calibration practice. It is worth reading through Jon Rista's CN Beta Test threads on both the ASI294 and 1600.
The IMX back lit architecture is an impediment to even substrate cooling, giving rise to colour gradient abnormalities, it is also subject to significant unmanaged AMP glow problems. ZWO has gone so far as to changing their marketing strategy for the 294, pitching it as an EAA camera (where it's sensitivity, with high frame video) negates the issues that haunt it's long sub AP performance.
So in terms of the original topic, there are big differences in CMOS camera capabilities and operational practices depending on which chip is used.
