Loaded up CN firmware (6.5.072S_0715) and checked for online update. Not there. Still prefer HRD over DV so going back to US firmware (5.8.056S_0420). Of note, I recently received an email from Apple requesting additional info on a bug I submitted long ago about Dark Dolby Vision with the Apple TV 4K. Maybe there is hope to be had.
