My TV label says Manufactured 10/2022, so I assume it has a WBE panel.

On the TV label: "MANUFACTURED" 07/2022 and later must be WBE.

Or in TV "service menu":
click the "Home" key on the TV remote control,
Start the TV web browser,
In the address line, type: http://webosapp.club/instart
"Yes"
Password: 0413
In the service menu
"12.OLED" - "Module Info 2" - **/**/**/**
00/**/**/** - WBC
08/**/**/** - WBE

No idea but Tv is very cool! I use it for gaming. lg
