Adobe HDR - ANY value in my standard world?

Nope

I think the addition of HDR editing is great, especially for those who want to take the most advantage of the fact that the majority of new TV and smartphone displays now support HDR. It really liberates the highlight details in the upper end of the tonal scale that have always been in many of our images but we haven’t been able to really see them.

Having said that…HDR is usually disabled when I edit. I also have an Epson 3880 printer, and HDR is of zero use when editing for practically any form of print. Although I also post to the web and social media, many of the popular websites are not yet set up to handle the HDR file formats that Adobe apps can export to.

As more websites and apps support HDR, I will probably do more HDR editing. But anything I want to make a great print of will not be edited in HDR, or I’ll do a separate HDR edit for print (using, for example, a virtual proof copy).

So, there is nothing wrong with not using HDR for now, and if someone’s primary medium is print and they rarely post online, there might never be a reason to enable HDR.
