I don't think that really means much, all of the (major) streamers are just being paid to play the game on stream for X amount of time/days when the game launches. It's not organic. Twitch is just another marketing spend for these companies. Most of the big streamers maintain the same average viewer count no matter what they're playing.
In this paper, we explore the capabilities, the current
prevalence and technical limitations of this new tracking technique
based on three commercial tracking solutions.
To this
end, we develop detection approaches for ultrasonic beacons
and Android applications capable of processing these. Our
findings confirm our privacy concerns:
We spot ultrasonic
beacons in various web media content and detect signals in
4 of 35 stores in two European cities that are used for location
tracking.
While we do not find ultrasonic beacons in TV
streams from 7 countries, we spot 234 Android applications
that are constantly listening for ultrasonic beacons in the
background without the user’s knowledge.
Currently, after #1 Just Chatting category with 445K viewers, Black Myth: Wukong sits at #2 with 246K viewers.
There are also some popular streamers which have streamed playing the game or the Gamescom event.
