That's not entirely true deadringer28. Back in January we were told specifically that 2015 models would get a 'lite' version of webOS 3, which effectively contained all the features even if it was not specifically called webOS 3. See here:

There was further word of the update in April, here:

But of course, there's no sign so far. Presumably it's imminent, however, as the 'lite' update to webOS 1 rolled out around this time last year. The sooner the better really.
On a related note, I was interested to see your reference to an HDR update to your set. I didn't know that was possible. How did it happen if I may ask?
