Do you use other settings in madVR or projector when displaying SDR or lower resolutions?
If you always leave madVR in BT.2020 calibration mode and also leave the JVC in BT.2020, then you don't have to worry about changing color profiles at all. madVR will ensure that all videos come through in the proper color. If you play SDR from another source other than madVR however, then you will want to change the JVC to rec709 color profile. Still probably keep 2.2 gamma and always 6500K color temp though.
From your info I estimate your NITS at about 115 nits in low bulb and about 160 nits in high bulb.
However, this would be with a new bulb and I forgot to ask about how many hours you have on your bulb, so your nits could be lower depending on how worn out your bulb currently is. The aspect ratio of the movie does not affect the nits since you always have the projector set up zoomed to fit the 16:9 screen.
Even in low bulb you have more than enough brightness. I only get about 75-80 nits on my NX5 in low bulb on my 140" screen, and with madVR HDR tonemapping it still looks excellent IMO.
Using 100 nits in madVR for your low bulb is probably still a pretty nice number to use. I wouldn't set it lower than 100 in your case, and raising it to 115 would only make your image a slight bit dimmer, but as your bulb ages, you will get much closer to 100 nits anyways if you aren't there already. If you do use high bulb then it is probably worth increasing the target nits number to around 150. But with as much brightness as you have on a 110" screen I don't think you need to worry about high bulb mode.
As far as the Auto DI, you can turn it on whenever you want. Most people like Auto 2 the most. It should increase the overall contrast if your image, but it could come at the cost of some artifacts like noticing your image getting brighter and dimmer as the scene changes. If you see this and find it distracting then you might choose to keep the Auto DI off like you have now.
As far as other settings that I use in madVR for SDR and lower resolutions, pretty much just the advanced up-scaling options (called NGU) in Chroma and Image up-scaling madVR sections. NGU is a high quality neural network (artificial intelligence algorithm) image upscaler and at least for a native 4K projector such as my NX5 can give a nice result on lower than 4K resolution content. On your eShift projector the difference from high quality upscaling wont be as drastic, but there is probably still some gain to be had if you are playing lower resolution content.
