When transferring 'Gran Turismo Sport' data to a PlayStation®5 console (PS5™ hereafter), if the game is installed on the PS5™ console before transferring data from the PlayStation®4 console, replays and Scapes photo data will not be transferred.
If you find that you are unable to view replays and photos after starting 'Gran Turismo Sport' on the PS5™ console, please try deleting the game data from the PS5™ console, then select 'Gran Turismo Sport' from the 'Select Saved Data to Transfer' screen accessible via Settings > System > System Software > Data Transfer.
For reference, please see more details at the following page: 'Data Transfer from PS4 to PS5 Consoles.'
Thank you for your support and please continue to enjoy Gran Turismo Sport!
