Nothing like the HD DVD vs. BLu-ray format war, since both Dolby Vision and HDR10 will likely survive (especially HDR10 since it's locked into the UHD BD specs and has to be used on all HDR content). But it should be interesting especially from a TV manuf point of view.

There's an interesting podcast on HDR that they discuss the differences between HDR10 and DV. The relevant part is from about 23:45 and last for around 11 minutes.

In a nutshell DV and HDR10 are very similar except obviously one is static and the other dynamic (DV). If you have a display that can get very bright then the two look almost identical. The two main advantages of dynamic HDR is that the dynamic metadata can be used for remapping certain scenes that come out too dim on HDR TVs with a lower nit capacity, to make them brighter. So DV is a winner for the lower end TVs like the Vizio (which can only get to about 600 nits brightness full screen and surprisingly even less than that on a 10% window). So for a higher end like the Samsung and Sony which are UHD premium certified, then that advantage essentially goes away.

The other DV advantage is that you don't have to worry about calibration standards since that is built in with the metadata.
