If you guys can not hear a difference between tracks on YouTube I’m thinking its you and your bias, as I can readily hear a difference.
The problem with YT videos isn’t not being able to hear a difference - I don’t think anyone but you has claimed that - but assessing qualitative differences. Because YT is lossy, there’s no way to know what information you’re missing. And of course that can make all the difference.
... sure its compressed some but not always compressed more then red book ...
Redbook CD is 16/44.1, by definition. Youtube’s bandwidth isn’t even close to that. By design. You or your system have issues if you can't distinguish between CD quality and lossy compressed audio such as YT or mp3s.
