All Atmos Isn't The Same

[Richx200]

I bought Top Gun Maverick (Blue Ray 4k Atmos) before it was streaming. Amazing video with great sound. When it was available steaming, I thought I'd take another look. While watching the movie, I started to notice that the sound didn't match what I remembered when I watched the Blue Ray DVD, what happened? I checked the settings and everything was working and where it should be.

So, I started to look into Dolby Atmos and found that all Atmos isn't the same. What is on Blue Ray 4k Atmos is True HD lossless and what gets streamed is Dolby Digital + lossy compress, stripped down. Atmos. Because True HD cost more bandwidth, hence more expensive to stream: some provides even charge more for 4k Atmos; which doesn't sound any better than 5.1 Surround to me

Why aren't the provides saying that the Atmos you are about to hear isn't True HD but DD+ and therefore is of lesser quality? I know that would mean they would have to be honest.

Just saying we should get what we pay for; what's next, streaming is the theater and calling it Dolby Cinema ?

It is not just the audio. The video stream is likely compressed to a lower bitrate than the one saved on the 4k Blu-ray too. This can occasionally introduce visual artefacts.

"get what we pay for" - If you want the highest possible quality buy the blu-ray.

I wish this was more widely publicised, known and/or that more people cared about it. Unfortunately, due to the convenience, streaming has already finished off most retailers of blu-rays. It is particularly galling that the quality offered by streaming is also inferior.
