I turn it off and on to see which changed. An indicator would be nice. Maybe an icon that I can hover over to reveal the original thumbnail and title.

I get where you are coming from. If I follow a channel then I already get a feel of what the content will be even if the title or/thumbnail is clickbait. Also you lose part of the channel’s charm. Exaggerations can be really funny.

It works a lot better for the trending section for unknown channels.
