I got madVR working with MPC-HC, which supports downscaling HDR videos to SDR displays. I guess depending on how the content was done, HDR does seem to have a benefit over the SDR version. However, in another example I have, it appears the colors are saturated too much.
But here's what I pulled from my "gold standard" videos.
In the HDR version, in some scenes, it keeps the color of certain parts of the scene more or less "intact". Like for example in the first images, the HDR version doesn't have a reddish tint the other one does. Though a "glaring" issue if you will, is that the HDR version appears darker. Or rather, the shadows are darker. This is probably more of an artifact that HDR still requires a high-contrast ratio display to work "properly"
