Update: Sony has offered a statement regarding the inability to archive twitch streams of Until Dawn broadcasted from PlayStation 4s.
Sony says Until Dawn's Twitch archiving was deactivated by mistake and should not be an issue soon. Here's the statement from Sony:
We are currently working on a fix that will enable archiving of Until Dawn Twitch streams as this feature was unintentionally disabled. We are humbled by the community reception of the game and are excited to see fans sharing experiences on Twitch and YouTube. We apologize for the inconvenience and will provide an update as soon as the issue has been resolved.

According to Twitch, Sony is blocking PlayStation 4 Twitch stream archiving of Until Dawn.
Using PS4 Share to broadcast "Until Dawn"? The publisher has disabled archiving for this game. We're reaching out to hopefully enable. ^JM

It's unclear exactly why Twitch stream archives of Until Dawn are being blocked, but we've reached out to Sony for more details. It appears to only be archives coming from streamers who are broadcasting directly from their PlayStation 4s using the built-in Twitch app. For example, the archive of our Until Dawn stream, where we played the game through to completion, is available to watch online here. Note that it is broken into a few chunks. Our stream was not broadcasted through the PlayStation 4's built-in Twitch app.
As previously mentioned, we've reached out to Sony for more details and will update this story when if and we receive them.
My assumption is that if Sony is actively blocking archiving of this game, it's because it wants people to experience the game live, as opposed to watching a rebroadcast. It's a game that benefits from live play – lots of jump scares, lots of important decisions that affect the fates of the characters. Despite that though, it still seems odd to go out of the way to prevent people from seeing the game played in an archive.
