There's a lot that goes that you don't notice, or that you easily forget about when you make a comment like this. The introduction of a gradient and accent actually enables and makes it more natural to use more eye-catching effects on the platform. For example, when a YTer says "subscribe", a rainbow (IIRC) animation plays on the subscribe button. When you like or subscribe, an animation plays that now has more color to it. These animations feel satisfying and I dare say have measurable impact. At the same time, the changes are so subtle that users hardly notice a change that they will have difficulty getting used to, and also already present components do not look out of place if they don't get refreshed. That is what an experienced design team is paid to do. Complaining about seeing no drastic change here is like complaining about engineers making no user-facing effect when they refactor the underlying systems in preparation for future developments.
