Nope. Native netflix only works at 480p on mars pro. In fact, none of apps ( prime, disney, hbo, works at 4k 444 10bits ). Best results with chromecast 4 on hdmi port, BUT no atmos compatibility and no sounds on netflix when start series or movies. My final choice: chromecast on 4k receiver ( marantz sr6015 ) and then to mars pro. Perfect image and sound now. Its a shame DANGBEI dont put decent Android version ( 10, 11 ) and native 4k within external dongle.
