Is there a problem?

Seems pretty normal. This "deviation" is more pronounced when your car has a dark body color.

Dark colors absorbs more heat which will eventually end up inside the cabin.

When was the last time you had your air conditioner cleaned? It may be the culprit why your ride's aircon is not an optimum efficiency. While you are having your aircon serviced, you may check your expansion valve and drier, they may need replacing for a better cooling effect. Good luck.
