Motor temperature too low most of the time?

Hello together, To my knowledge, it is the goal of an automobile/engine manufacturer to bring the oil temperature to approx. 90° as soon as possible. I think the display in the car is determined by the coolant temperature sensor, which should be in similar temperature ranges as the oil (or?). So the display should move to the middle area of the display as soon as possible – so to speak horizontal position – because that’s where the radiator fan starts. a Fiat Bravo 182. Is it now normal with the model that the display is most of the time far below the horizontal position? Does this mean that the oil is also well below 90° and is therefore not in ideal condition? Thanks for reading and your help already. Greetings
