In my experience, poor/incomplete applications are something you have to keep an eye out for regardless of what platform you're dealing with.
I've seen audio stutter on a smart TV running the Netflix streaming app, and similar stutter on a network-enabled Blu-Ray player running the Amazon Video streaming app. I've seen 4K playback cause occasional stuttering in the Amazon Video app on a smart TV. Disney+ group playback is currently unsupported on PS4, but is supported on Xbox One. A few years ago, the PS3 Netflix app supported 1080p, whereas the Xbox 360 Netflix app only supported 720p. I've also seen the Xbox One YouTube app insist on playing a video at 720p or lower, despite that Roku will play it at 1080p (perhaps an issue with only a certain codec being available at that quality?). I've seen a paid video service with an iPhone app with completely broken Chromecast support (they fixed it a few weeks after I filed a bug report).
