I'm sorry that I don't really have an answer for you, but I really want to correct the weird false information from the previous person's answer... I do not know if it supports HDR Passthrough. I'm assuming you know a decent bit about Audio Video stuff, otherwise you wouldn't be asking about HDR Passthrough Support, and thus obviously know that yes, it does matter. For anyone else reading the answers: Passthrough Support DOES MATTER. The Sound Bar DOES CARE what signals you are passing through it. If the Sound Bar does not support HDR Passthrough, then your player device (bluray, chromecast, etc) will not even TRY to play the HDR content. It'll just play the default 720p, 1080p, or 4k content. The audio equipment, be it a receiver, or a sound bar, need to be capable of determining what sort of content is being played, so that it can be HDCP compliant. If it is not compliant, guess what? You get ZERO VIDEO to your TV. "Passthrough" is not just something like simply allowing the raw data to pass directly through.. it has to make a 'handshake' with every component in the chain to maintain encryption for HDCP. And part of that process is identifying the capabilities of each component in that chain...
Sorry, there was a problem. Please try again later.Okay so question only relates to your Television picture for the HDR format your TV is displaying. Soundbars don't know what HDR format your using nor will it care even SDR formats with the right digital audio codex will give your home entertainment system for best audio sound that can support. What the high end Soundbars need is the highest digital formats that send each audio signal to all the channels from the audio encoded in your content for each speaker. Passthrough is more about the uncompressed audio signals that comes through an eARC HDMI port. What you want from this sound bar is DTS:X and or Dolby Digital Plus or Dolby True HD support. You want these codecs from your content so that you can get Dolby Atmos. It only the content creators that will decide the codex used. A Standard DVD will have Dolby Digital not have Dolby Atmos support. When you use arc hdmi ports that audio is compressed and audio signals are only sent to sound bar only one way from device it's connected to. I hope this helps and their are video you can watch for more information.
