Would you be kind enough to check something?  Double click an hdr.iso in Windows Explorer and navigate to the new drive letter mount.  Open BDMV folder.  Right click index.bdmv and select to open with VLC.  What happens?  If it opens and envokes HDR mode (Windows HDR switch remaining off), I'm going to give it a go and do some comparisons. 

Apologies brazen1, I have been buried in work since yesterday so haven't been able to test this yet. Hoping to do it this weekend.
 

Wow, I have a hard time believing that. I wonder how they balance this with all of the Intel iGPU users who don't understand why this doesn't work with Intel? Intel iGPUs would be pretty common among the average VLC user, as it is still the most popular media player out there.

I'm not sure, to be honest with you. Maybe there is some technical downside or lack thereof that my limited knowledge on the matter has not been able to determine as yet. Without a doubt, more tests are required. It's promising though.
