Why do I say that? It is simple, too many differences with streaming audio these days. With cable/sat/antenna, most sources are in DD5.1 audio with a few still just doing stereo. But in streaming that isn’t the case at all. For live streaming services like ATT TV, Sling, YouTubeTV and others the normal is stereo. Only ATT’s live streaming offerings have DD5.1 audio, all the rest are stereo. If you only use your TV’s speakers or a simple single soundbar setup you probably wouldn’t notice. But for those that have sound systems capable of DD5.1 and better audio, you really do. For OTT services like Netflix, Prime and others it is a mixed bag. Netflix & Prime are pretty consistent in having at least DD5.1 available. For others, it is much different. Hulu for instance has some of their VOD offerings with DD5.1 audio but not all. And it also depends on which streaming device you are using. For instance, on AppleTV boxes Hulu has no DD5.1 at all yet the same show on Hulu on other boxes does. IMO, there is simply no excuse for this at all! TV channel apps vary quite a bit too. Some have DD5.1, some don’t, none actually say whether they do or don’t except maybe in some obscure FAQ on their website. Most modern sound systems help out with this mess by offering Dolby ProLogic massaging to stereo sources, but even that isn’t consistent depending on box. Some streaming boxes report DD+ to the sound system regardless of source materials actual encoding. And many sound systems won’t do ProLogic over DD+ so you don’t even get faked surround sound. In this day and age almost all relatively new source videos are at least encoded with DD5.1 audio which makes the lack of it from streaming apps just laziness or incompetence on the providers part IMO!
