yeah, thanks for the clarification.
I more meant picture quality wise, Dolby Vision is the stronger option because it's controlled, with a single mastering display, and specific hardware determining the correct roll-off for each set it's being displayed on.
HDR10 is the fucking wild west, and while it's more adopted at this point, the results of different discs, players, and TVs, are all wildly different.
So Dolby Vision is the stronger STANDARD, at the moment. Though HDR10 certainly has more support (UHD discs in particular... streaming services seem to be supporting DV a bit [Vudu exclusively using DV], especially Netflix, but we'll see when Netflix/Amazon get their next wave of HDR up). And of course, Dolby Vision is proprietary vs HDR10, which would slow it's adoption, especially for hardware that requires the chipset.
