My player supports DV, my TV doesn't. I have no plans to upgrade the TV in the near future just to get DV support, but when I do upgrade it will be something I look for (along with support for as many other HDR formats I can get at the time provided they exist alongside the other features I'm looking for). HDR10 already looks stunning, but having more compatibility is always a good thing. The biggest draw for me in my next display will be going to an emissive display, so once either OLED, emissive QLED, or MicroLED become affordable in a 75"+ size I'll pull the trigger.
