You are comparing a 10-bit variable metadata format to the 12-bit within Dolby Vision. There is a measurable difference.

There is no such thing as a 12 bit tv panel so no.

The main thing is the dynamic metadata of 10+ and DV versus static of regular HDR10.

Different TV's can display a higher percentage of the bt.2020 spectrum than others. The higher end ones do get more color out of Dolby vision than hdr10+.

Samsung panels are too good and tend to have the same/better color gamut as any other high end TV. For instance, the Q90 covers about 1.2% more of the 2020 uv spectrum over the LG C9, and there is no change for the CX as it is the same panel. The Sony A9G OLED also scores worse at about 2.2% less color gamut. The 2020 Sony X950H scores worse in both by 2%+ as well.

So really, those panels don't make much use of the extra color volume over any other set. And on top of that the OLED's can't get bright enough to begin with to take advantage of the Dolby Vision expanded colors.

But yes, in a perfect world the top TV manufacturer would support both, but they don't. And given that HDR10+ is royalty free and DV is not, it's hard to blame them.

So that leaves you with Vizio that supports both. Quantum X is a good set, gets very very bright and also smashes any of the above mentioned TV's in the rec 2020 colorspace, +9% and +11% over the above mentioned Q90.
