It's really conservative, but what your gauge is displaying is within OEM acceptable limits.
My limit on the expressways is 105-110kph on the speedometer if I want to stay within 100kph limit of the expressways.
Table below shows the actual speed (left side) as read directly through the OBD port by a Toyota Tech Stream/GTS diagnostic tool doing active test VS the acceptable speed display on the speedometer(right).
