PS4 Trainer can attach on Backported update?

[easy]

PS4 Trainer can attach on Backported update? But CUSA and Update like 5.00 is matched.

Example:
PS4 Trainer has Assassin Creed Valhalla CUSAxxxxx for 5.00 update

I have installed same CUSAxxxxx but;
Assassin Creed Valhalla 1.00
Assassin Creed Valhalla 5.00 Backported
