Exactly. Even though there’ll absolutely still be displays that won’t really do HDR, they’ll soon enough be able to handle that as input signal and then just map it down to their gamuts. Just like 6bit displays still take 8bit input etc. “HDR” will just become the standard colour format and displays will map it with varying degrees of accuracy. (Many already do this.)
That’s awesome! I wish I could’ve used this information with my dad, who was partially deaf, to try if it could’ve helped him. Unfortunately he passed away some years ago so we’ll never know. I’ll keep this in mind though, so I can suggest it to others.
