Why Does Lightroom Classic Show Different Colors Before and After?

Hi. I've encountered some odd behavior in Lightroom Classic. I assume it's not a bug but normal behavior, yet I want to make sure. 🙂 I have a photo loaded, in the Develop module I reset all edits and then set the current look of the photo as the "before" preview. I press \ to show the photo before editing, and the colors are different before and after! Isn't that strange behavior? Check out the video I recorded. Do you have any ideas why this might be happening?
