In ICC aware applications, makes zero difference.
With displays that don’t have high bit paths, the farther you move from a native behavior, the more banding that can result. But you have a high bit panel. So you can set the calibration for a 2.2 gamma.
when i do i get the banding (just tried it again).
I also tried it with the gamma set to 1.8 and got extreme banding there too. So, it seems that I can only get smooth curves with Native Gamma....
Here is the issue that led me to look for better settings than I'm using:
When prepping images to save for web I usually convert to the monitor profile (I've been around the bush a million times with converting to sRGB and and when I convert to sRGB and try to save for web everything gets darker, more contrast, and a shift towards red. it doesn't happen when set to monitor profile and unchecking sRGB in the save for web box). So anyway, when I save for convert to that profile, something that is 255,255,255 white goes 247, 247, 255. I noticed this when viewing the images on different displays other than my "calibrated" one that those whites were now slightly blue. The thing is they look exactly the same as 255,255,255 white on my display (like if you drop that 247,247,247 color box onto a 255,255,255 background it blends right in).
hmmmmmm
