After several months of trying out different methods for dealing with this problem, I finally gave up and disabled Windows scaling entirely (set it to 100%) and reduced the screen res on my Wacom Cintiq Companion 2 from 2560 x1440 to 1600 x 900. I was running into UI scaling to problems with too many programs because it wasn't being used consistently by various developers. Turn off UI and reducing screen res forces all programs to behave 'normally'. I know 1600 x 900 is not terribly high, but it's still higher than what I had on my old tablet computer (HP tm2) and, to be honest, it looks just about right on a 13-inch tablet display. Not tiny at all and a comfortable layout and workspace. (Unlike when using Photoshop's 2015 cc's 200% 'geriatric' scale preference for this computer.) I'm not completely happy with this solution because I'm using almost half the screen capability of this tablet computer but I have to say, it's nice to see Photoshop (as well as many other graphics and animation programs I use daily,) look normal and with plenty of usable workspace again. Another plus to consider is that reducing the res may extend the battery time for the tablet since it's refreshing about a 1/4 of the resolution data. (Note: I don't know that for certain. Could a more tech-saavy person tell me if this is a valid assumption or just wishful thinking. Thanks.) It's now my opinion that, until all program developers can agree on a common implementation of UI scaling for high pixel density screen, disabling UI scaling and reducing screen resolution to a comfortable value for the actual screen size is probably the most reasonable fix at this time.
