But i think that is not true anymore. Have seen more mixed results and av1 was most of the time smaller.
Will look, if we can collect data about it once new AV1 encoded videos are available(no new AV1 encoded video since 2020-02-23 in the "Popular Right Now" playlist)

Tracker how many AV1 encoded videos are in the "Popular Right Now" playlist per day

I can see that making sense. Given how YouTube distributes encoding, it would be hard to run AV1 at higher quality/efficiency levels with libaom. So at the same MIPS/pixel, they may have needed to use a higher bitrate than with vp9 to deliver the higher quality they wanted to with AV1. Which makes sense as their goal was to push AV1, not to use it to deliver lower bitrate or higher quality content overall (then they would have just raised vp9 bitrates).

As we're getting faster and better encoding, I would expect the AV1 bitrates to drop while maintaining quality.
