As DUPLEX continues by adding 17 More PS4 FPKGs to their Holiday 2020 Extravaganza consisting of over 30 releases thus far, in PS5Scene news developer andshrew made available a PlayStation 5 Backwards Compatibility Status list (PS5-BC-Status.json) based on extracted data from Sony's official PS5 API (Application Programming Interface) utilized by Library.PlayStation.com. 
Download: supreme-enigma-master.zip / GIT
This comes following the PSN API PHP Wrapper, PSN API Python Wrapper, PS4 Games on PS5, official Backward Compatibility Games Page, PS5 Backwards Compatibility Update via Remote Play from PlayStation 4, The Ultimate PlayStation 5 FAQ and the DualSense on Windows API.
The PS5 Backwards Compatibility Status currently contains 15,681 entries for PlayStation titles in multiple regions... and from the README.md: PlayStation 5 Backwards Compatibility Status
Sony has an API for retrieving the backward compatibility status of PS4 titles when played on a PS5 system. This API is directly utilised by https://library.playstation.com/ for displaying the status against the titles in your library, and for determining whether or not the option to allow you to download it to a PS5 should be available.
This repository contains a extract of responses from this API created by submitting known PS4 title IDs (ie. the CUSAxxxxx codes) to it.
This data can be viewed in a friendly table format at https://andshrew.github.io/supreme-enigma/ courtesy of GitHub Pages and DataTables.
The raw JSON data file can be accessed here. The API can return one of three statuses for a title.

| Status | Description |
| COMPATIBLE | To play this game on PS5, your system may need to be updated to the latest system software. Although this game is playable on PS5, some features available on PS4 may be absent. |
| BOOTABLE | When playing on PS5, this game may exhibit errors or unexpected behaviour and some features available on PS4 may be absent. To play this game on PS5, your system may need to be updated to the latest system software. |
| NOT_COMPATIBLE | Only playable on PS4. |
| N/A | No information available in API (mostly old alpha, beta, and demo titles). |
- These descriptions have been sourced from the PlayStation Store.
- Due to running a list of known PS4 title IDs through the API to generate this extract there are many titles which are old alpha, beta or demo titles which do not exist in this API and so return no response.
All such titles are not compatible when played on the PS5 but as they are not explicitly listed as such by the API I have assigned them an N/A status (ie. they do not exist in the API).
