If a YouTube video is monetized, how can I see if the revenue goes to the channel’s owner, YouTube or a 3rd-party, if I'm not the video/channel owner? [closed]

I know that:

1. One can see if a video on YouTube is monetized if one is the video/channel owner.

2. One can see if a YouTube channel is monetized even if one is not the channel owner:

   When you're on view page source [of the YouTube channel], hit CTRL+F to open the search box and search the value "is_monetization_enabled".

   If you can read
   "key":"is_monetization_enabled","value":"true".
   then the channel is monetized.

   If you can read
   "key":"is_monetization_enabled","value":"false".
   then the channel is NOT monetized.

3. One can see if a video on YouTube is monetized, even if one is not the video/channel owner:

   To check if a video is monetized, go to the video's page, view the page's source code, and search for the string yt_ad. If the string is present and set to true, the video is monetized, else it's not.

isthischannelmonetized.com mentions:

Seeing ads on a video or seeing the “yt_ad” string in the page source code doesn’t mean that the video is monetized by the channel’s owner – it could be monetized by YouTube itself or by a third-party.
