No, I don't think it's worth spending a huge amount. Out of curiosity, I purchased an ethernet cable that several members here touted on Amazon, easily returnable. That's when I found out ethernet cables can sound different. It made my system sound worse than the standard issue provided by my cable company, so back it went. I was not about to wait several hundred hours to let it "break in". I then tried DH Labs Reunion ethernet cable as it was also returnable. I think it sounded better. It definitely looked prettier, so I kept it.
