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.  

 I would guess there is some type of new API available. But, none of the media player developers seem to be aware of this. The Windows VLC renderer is also Direct X, so it would be considered common as Windows media players go. There are some video processing options in VLC that aren't available in DVDFab Player. You might want to check out the advanced settings. I think the default resizer is Bicubic, for instance, and there are at least a couple of better options, if I recall.

If the HDR metadata is getting to the display, I can't see any downsides. It could be doing an HDR -> SDR conversion, so you should be certain you are getting HDR content. HDR mode would certainly not engage unless there is a bug in VLC, or unless you toggled the Windows OS HDR switch.
