Do I get native 4k ULTRA HD?

Yes. Director Todd Phillips originally wanted to shoot the film in analogue, ideally even 70mm. But after testing Arri's large-format digital cameras, the cinematographer was convinced to use the Arri Alexa 65, whose giant chip can deliver up to 6k footage. The resolution of the raw footage eventually stopped at 5.1k, with these then supplemented to a lesser extent by 3.4k and 4.5k clips from the Arri Alexa Mini and LF. All of this was downsampled to 4k for post-production purposes, which is the resolution the master eventually stopped at. The UHDBD transfer of Joker therefore takes the image information from the native 4k. In addition to higher quality compression, this allows it to offer significantly more detail and sharpness, which are then complemented by an even wider brightness and colour space thanks to HDR and WCG. These are all technological advantages that neither Blu-ray nor most conventional cinema projection can match, and so it's safe to say that the home cinema version of Joker looks the best of its entire distribution chain.
