There is a misconception that an aero road frame can offer a drag reduction of 3 to 7 watts when riding at a speed of 40 km/h compared to a normal gravel or road frame but those improvements are not really visible on casual rides. The aerodynamic advantage comes into play whence one is fully clad in aero gears and riding the bike at a higher speed. When considering a daily commute, the difference in the aerodynamics of gravel and road frames is minute.
