the gauge spot is buffered - it stays in the center from 75 to 105 degrees, and does NOT move when temperature is going up and down while engine is running... i do not remember exact numbers, and have no access to my files on vacation, but the needle is buffered, the actual temp is constantly moving as thermostat opens, closes, opens again... yours seems to be running a bit cooler, and while it is not overheating, which is good, it may have its own issues of a under-warmed engine...

however, if the needle is within the black and is NOT in BLUE or RED, you are ok, the engine is designed to run in those numbers...

check your VIN, see if you have a cold or hot climate version (not cold package, cold climate), maybe that could be related to your needle to be slightly cooler...
