Icons endpoint does not match icons seen in Feedbin

I'm subscribed to these youtube feeds:

https://www.youtube.com/feeds/videos.xml?channel_id=UC9PBzalIcEQCsiIkq36PyUA

This is how they show up in Feedbin

However when I call the v2/icons.json endpoint I'm inly getting

{"host":"www.youtube.com","url":"https://favicons.feedbinusercontent.com/22f/22fede5b3794b820911f31de9971009c7498bcdd.png"}

which is the generic Youtube icon and not specific to the feed. Is there another endpoint that I missed or could you add the actual icons somewhere?
