Your last statement:

One thing I am taking away from this conversation is a user is adamant leaving the Windows HDR switch enabled all the time has no ill affects on any GUI's or Windows Desktop usage.  That to me I find mind boggling but chalk it up that differences in hardware must matter even though we use the identical GPU.  Also don't understand the same user is decoding and rendering HDR using PDVD 18 while not meeting PDVD's requirements?

Is actually the answer to your first statement:

I'm not really sure what we're trying to discover here

We weren't really trying to discover anything here, other then some of Mark's claims which, at the time, were standing contradictory to what we had learned some pages back, which are slightly more clearer now, although there still stands some discrepancy which is beyond the scope of our understanding at this point.

Where you stated "I find mind boggling" and "Also don't understand" is exactly where my conversation with Mark started, and pursued. As I too found certain things Mark stated as mind boggling & didn't understand, and wanted to find out more.

Nevertheless, your assessment is entirely accurate. We didn't really discover anything new we didn't know, and DVDFab v3 + PDVD 18 continue to be the correct solution for the vast majority of us. Mark's setup & preferences are slightly different then ours which does explain some of the claims, but not all. Which we'll have to let be at this point. It is, what it is.

Until something changes, improves or different comes along.

Edit:

Just out of curiosity, does anyone know if Kodi has any future plans for UHD HDR playback with it's internal player? I'm not exactly sure what kind of costs, licensing, effort is required for this so please take my question with a grain of salt. I think the demand is sufficiently there and steadily growing each passing day, but as I said, I'm not entirely sure what such a capability entails. 

Thanks.
