The latter. “Video spots” refer to video clips displayed in the embeddable player to indicate when ad breaks are playing on the twitch.tv channel. The image above is a still image from one of these videos.

Good question, we could have made that clearer. This change is slowly rolling out over a short period of time to make sure there are no issues with the implementation. Therefore, there will be some time when both the purple screen and the new experience can occur, even for the same user. Eventually, the purple screen will be phased out entirely.
I will also pass along your additional feedback to the team working on embeds, thanks!
