Beyond just standard High Dynamic Range (HDR10)... the Dynamic HDR (their words, not ours) means each scene or even each frame can have its own values when displaying light and dark areas... unlike HDR which just applies one set of value for the whole movie.

The difference with Dolby Atmos (or Dolby Audio) and DTS:X.... With HDMI 2.1 it's uncompressed. So, if you have the audio gear, your soundtracks should carry more data which means better sound, less latency (delays) and less digital glitching

Audio Return Channel (ARC) is great. Enhanced ARC is better... so with the full bandwidth of video, audio and Controls coming down the wire your (HDMI 2.1 e-ARC) Home Theatre AV receiver or sound bar will sound better than ever.
