If you're watching mostly 1080p at 1080p, then this is basically passthrough. If comparing to Kodi VideoPlayer, it simply renders pixels less faithfully. If you switch back and forth long enough, you will notice very small differences in color and occasional noise in VideoPlayer, but it is not a major change. madVR should also be slightly sharper, but this can be difficult to detect. But that's how the content was mastered. If you want it to be sharper, sharpen the image. If you want less noise, use artifact removal. But, mostly, the pixels are being rendered faithfully without adding any artificial detail.
If upscaling 1080p to 4K, you can indeed add detail to the image. Image upscaling will approximate what a low resolution image would look like if it was a high resolution image. There are four times as many pixels in a 1080p source upscaled to 4K. Unless you use Nearest Neighbor for upscaling, those new pixels will add detail to the image that was not there previously.
If you scale chroma separately, the chroma layer will be slightly lower quality. This is not overly important when doing a large downscale, so you can check this if you need to save resources. The only thing important is the quality of image downscaling. I would recommend using SSIM 1D 100%. If you select this, you may be able to uncheck the chroma quality checkbox with your graphics card.
As for HDR -> SDR conversion, it is completely up to experimentation. There are many settings because it is a work-in-progress. The setting "dumb - convert gamut late" is popular, while there doesn't seem to be consensus on the best scientific method. The target nits is like a brightness adjustment, and you can use any value you want, as long as the image looks good to your eyes. There is no scientifically accurate value. Higher target nits will crush the low end in attempt to increase the detail of the specular highlights at the top end, but this can lead to black crush at high enough values.
I don't know what you mean by having madVR settings on top of everything all of the time. Just close it if it is stealing focus from other windows.
