A:Answer Best Buy just adds fxza to the end of the model number. These are still the same as KU6300 models elsewhere (although I'm not an expert on what panels are offered per each model. Samsung may well use a panel lottery like they've done in the recent past for this model as well).
The KU6300 supports HDR10, but does not support Dolby Vision.
It's an 8-bit panel, not a 10-bit panel.
It doesn't have a wide color gamut, like other HDR tvs. It may be wise to invest in a higher-tier model that has those features, in order to get the most bang for your buck, especially if you're buying this tv with the purpose of supporting all the HDR and 4k content (both movies and tv shows, both streaming and physical media, along with gaming) coming out over the next few years.
