I need help evolving from 'poking at settings' to 'knows what poking at settings does'

Been using MadVR for a while now for HDR>SDR tone mapping on my Projector and I'm wondering if I am missing out on picture quality because I don't understand the settings properly.

Windows 10 - 64-bit
i7 - 16gb ram - NVIDIA 1070ti
madVR v0.92.17
LAV - 0.70.2.81-git

- My Calibrated Screen/PJ combo is hitting approx 70 nits with a rec.709.3dlut for Gamma 2.2 and I have this chosen in the calibration section of MadVR. I don't have any other 3DLut files generated.

- For HDR>SDR I am using shaders with a target peak of 200 nits, BT.2390 curve, balanced color tweaks and high highlight recovery.
I have 'measure each frame's peak luminance' checked but not sure if it works with NVIDIA CUVID decoding.

I wondering about how much I 'dont know' and if I'm getting less than stellar results with this config.

I 'think' my picture looks good, but without having any other point of reference I feel a bit in the dark.

- For my 4k HDR BT2020 content, should I be using a different LUT?
- Should I have Gamma processing enabled?
- How do I know if I am crushing blacks or if my highlights are right?
- How do I enable dynamic peak luminance adjustments?
- Why does my cat drink out of the toilet not her water bowl?

So many questions.
