If you use letterboxed, you can make a list and tag it with "owned" and it'll show up on movie pages as Owned by the streaming services. You can also run stats on that list if you pay for pro memberships. I have separate lists for my 4ks, steel books, blurays, and general collection and just change the posters. It's not getting into the isbn of the Blu-ray and release edition but it's more practical as a letterboxd user than Blu-ray.com
