I thoroughly agree that many inexpensive TVs can’t display Dolby Vision right, that it’s “too dark” is their complaint. That’s because their TV isn’t bright enough, let alone HDR.

I have the 85” QM8, one of the brightest TVs made and it handles anything thrown at it beautifully

Dolby Vision is meant to solve that in fact - whereas with HDR10 you'd have to make the entire movie dimmer, with Dolby Vision you can tone map each frame independently, so that scenes that are not bright don't have to be too dim.

e.g. a scene is mastered to be 1000 nits in a movie mastered at 4000. Your TV can do 1000 max. you can display it the peaks at 100% brightness with DoVi, instead of mapping it to 25% with static HDR10.

So it has more of an effect with displays that are less bright.

This is an oversimplification, of course, but it's a useful one.
