It sounds bugged if you are getting crushed blacks at higher target nits. It should be the same.
Part of the problem is that madVR may send a value to the display that is supposed to be shown at an exact nits and the display's tone mapping curve may be designed to show the same PQ value at a different brightness. I'm not sure how the Panasonic "HDR Optimizer" gets around this. It only seems to impact the top of curve in the screenshots I've seen. I would think this feature would only work well for displays that closely follow the PQ curve and roll-off.
Edit: I looked at a review of the Panansonic pre-tone mapping feature that also used an LG C7 and it was tone mapping the result to a preset of 1,000 nits. So it was actually above the brightness of the display when the reviewer was glowing about its effectiveness.
I don't know how sending a signal with an altered brightness response is tone mapped by a display expecting a standard brightness response from a standard PQ source.
