Thanks for the save, I was able to test all of them on the PS4 blank profile and everything worked fine. Then I used it on a blank PS5 using the cross-save function and every trophy again worked fine. As already mentioned the trial game will only pop a few trophies and furthermore will create the conflict save issue (not sure why).
I always made sure the following:
1. Start PS4 game version
2. Upload PS4 save
3. Continue PS4 save
4. Do the requirement to pop the trophy
5. Quit to the game menu
6. Close the game
7. Start the PS5 game version
8. Download the save to PS5
9. Continue PS5 save
10. Do the requirement to pop the trophy
11. Quit to the game menu
12. Close the game
13. Rinse and repeat the same steps from 1-12 and there should be no issue. On the off chance it does have that annoying conflicting save issue, just delete all the saves and re-copy and redo the transferring process from SW to your USB etc.
Hope this helps clear up what is required and gets people whatever they need
