I ... really don't see much usefulness changing part of the game UI like this having any benefits for user. Even if you are a new user, you're always seeing pack advertisements somewhere. Whether it's from the launcher, a pop-up from the main menu, or browsing the gallery and seeing user-created lots/households with differing icons for missing packs on your end (if there's a sale, it also indicates the sale percentage above), there's very little chance a player will not be able to find said packs.
I also don't have much interest with the UI addition 'shine' indicator based on user interaction, as I don't believe it should be there in the first place. To further critique and maybe suggest that, no, I would not like a toggle for this UI as a compromise either.
