Amazon actually does have a report that includes what its automated mechanisms currently consider as authoritative data for all of a 3P Seller’s Offer-Listings in its Global Catalog - the CLR, or “Category Listing Report;” there are reports in various discussion fora that the “Title Truncation/Item Highlights” Initiative (that’s “Dogtamerese” - in internal "Amazonese,’ it’s known as the “Modular Title Format” Initiative) has yet to roll out to all of Amazon’s ‘over-arching’ categories, and so some CLRs have apparently not been updated, but in your place I’d download the ‘All’ selection & check to see if Column J’s Human-readable Header (Row 4) is “Item Highlight” - as that’s an indication that that it has been updated.
There’s a 032025 SAS post here, including our friend @Old-Timer’s link to the Inventory Reports Dashboard where CLR/RFRs can be downloaded, that explains a bit more:
Originally, Amazon limited access to CLRs by default, requiring sellers to open a SeSu case & request enabling of the download capability, but some years back it announced that it was going to be made freely available to all.
Still, I occasionally see reports of folks having to open such a case, so it’s possible that you might have to as well.
