In any functional OS, such as Manjaro Arm, neofetch will display the Hardware Revision. Here is the neofetch for my RPi 4b 4GB showing it is Rev 1.2

Since the RPi 400 still today with the latest firmware won’t run the linux-aarch64 kernel but will run the linux-rpi kernel, I am betting the 32 bit OS will run on your RPi 4b. If so, I think there is a good chance that the firmware is out of date.

If your RPi 4b runs on 32 bit, then you can decide if you want to flash the firmware.
Here is how to do that, plus a couple of other tips.

will display the current firmware version. There are two parts of the firmware. It displays the bootloader first, then the on board VL805 firmware version. The latest on board VL805 firmware is 000138a1

You are on your own on the decision to flash or not.
