What display do you even have? 20 nits is like really low most monitors don't even reach that low. I have mine at 80-140 nits most of the time, except for games where I prefer higher brightness. SDR content is mastered for 100 nits. LCD Monitor calibration is usually to 120-140 nits. VA panels can take lower brightness better than TN/IPS since their black levels are closer to Plasma than the others.
BT.1886 is better than flat gamma function I agree. I have mine around 2.0 for shadows, 2.2 midtones and 2.35 highlights. Then fine-tune from there with madVR. There is no fixed setting for everything it depends on the source material. Some video looks better with BT.709 curve, some looks better with pure power.
Whatever you calibrate to, make sure that black levels 1-2 are visible but just barely distinguishable against 0 black and 254 white is distinguishable against 255 white.

@ Shocktrooper
I have a Panasonic 50VTW60 Plasma. And wrote so in paranthesis somewhere  . I use 40 nits because that is the limit for this model and size for fullscreen white luminance. Anything higher and anime and other high APL content looks offensive to me, due to ABL (aka dimming for large bright areas). For movies I could go higher, but I can't be bothered atm to have a third profile on the TV itself and 2 3D LUTs for madvr. Even though the difference between anime and movies, or high APL vs low APL content warrants it.
The 20 nits are for normal monitor use in the dark. I can't go much higher, without it being very fatiguing. The white links to lagom look plenty bright to me. In fact I think I need to reduce it a little 
Brighter room is not an option, because then everything looks boring.
BT.709 doesn't actually specify a curve though. Power gamma was always just an assumption. And even that leaves options for how to deal with non 0 blacklevels.
I gather from your response though that bt.1886 remains a good choice. Black crush is already what I paid most close attention to, and a major focus of the last days of calibration and what my colorimeter struggled most with 
Near black performance is so important, but sadly very hard to get right. And at some point 0.002 nits are just not dark enough, so hopefully I'll know when to give up.
Btw, its impossible to get white crush on this device. You can set it as bright as you want. Always wondered why some devices even allow that to happen. Though of course I could fuck it up during calibration, but in that luminance range I have no accuracy problem with measurements.
Thx btw, very appreciated
