MKV Files and HDR

Hello,
When I rip a 4K UHD blu-ray in makemkv, does the mkv file actually have HDR? For example, the picture appears exactly the same in VLC player if HDR is enabled or not in Windows. When I enable HDR in Windows, I can see the change in Windows. Plus, my display briefly shows the signal has changed to HDR mode. However, there is no difference when playing a mkv file in VLC.

If you look at the .mkv file with
MediaInfo, the video section will list if the file has Dolby Vision and/or HDR10. For example, here's a movie with only HDR10:

I don't really use Windows or VLC so I can't really make suggestions about them.

I don't know for sure, but maybe VLC automatically issues some tonemapping if it finds a HDR source with a non-HDR display.

I'm not sure what you mean by that. I know my display is not in HDR unless I enable it in Windows. Like I said, there is no difference in the picture if HDR is enabled in Windows. I understand VLC supports HDR and dcoke22 confirmed that mkv files contain HDR.

You could try
MPC-HC with
MPC Video Renderer instead of VLC.

Windows will have the option to enable HDR, even if the display doesn't support HDR. Does your display support HDR?

MPC-HC player with madVR Renderer and you need display with HDR support, check hardware specifications, user manual.
