Unless you’ve done a side by side level matched AB to the master your comment is only an opinion, nothing more.

It's "NOTHING" like it? That's a bold
statement when we're talking about two different LOSSY compression formats. An update to the compression protocol hardly makes it night and day different. It's STILL a lossy
compression format. It's purpose is to save bandwidth (money) in transmission. Even poor quality compression protocols sound good if you give them enough bits, after all. Until Netflix updated their server end transmission, it mattered not. I'm not downplaying Netflix's higher quality audio transmissions they now offer. My POINT was that the Shield has not updated the App to something the AppleTV 4K has had now for many months, which is not only DD+ underneath (The ATV converts it to PCM internally first), but Dolby Atmos support for shows like Altered Carbon. I probably should not have used the term "DVD" there as most DVDs had very low bandwidth Dolby Digital on them, where you could potentially hear a quality difference. With the Blu-Ray DD rate of 640kbps, however, I cannot tell the lossless track from the lossy track in casual listening, certainly not to where it bothers me.
However, I'd LOVE to see someone do an A/B/C style 3-way comparison between 640kbps DD and a similar streaming rate of DD+ and the LOSSLESS version (which is present on most Blu-Rays and so it's easy to get a signal to compare. It's hard to get a DD+ version from one of these discs since they mostly use DD, but you can easily make a DD+ track using software tools). The bandwidth is neither here not there to the consumer that has enough of it. The question is whether the consumer can HEAR a difference between 640kbps DD, DD+ (at whatever rate you want since I maintain 640kbps is transparent) and the lossless version. I'm not saying someone can't tell the difference (I've certainly never heard one at the 640kbps DD rate at any rate; I'd be less sure of lower rates, but that was no my original point).
My original point
was not to compare compression ratios, but to point out that the update to the Shield does NOT include Dolby Atmos support from any major app like the AppleTV has and thus it's INFERIOR (no matter how high the bitrate) to the AppleTV's capability when watching the same Movies Anywhere movies or even Netflix. If I watch Altered Carbon on the AppleTV 4K, I get Dolby Atmos (with a DD+ carrier converted to PCM). With the Shield I get 5.1 (not even 7.1) with DD+. THAT is what I'd call "nothing like" (actually I wouldn't use THOSE words even there as of course they're "something alike", just less rendered channels). In fact, until I got my newer Marantz 7010 AVR to replace my 2006 AVR, I could not even get more than stereo from the Shield as unlike the FireTV, it does not convert DD+ back to DD for older equipment leaving me with 2-channel sound. Why? Its saved NVidia a few cents per unit in licensing costs to convert to the older DD. I can blame Dolby. I can blame Nvidia. Either way, I had 2-channel sound until I upgraded the AVR.
In other words, I don't care about the Shield update changes because I'm not going to choose 5.1 over Atmos (when I have both devices present) and thus the Shield apps will NEVER get used.
