No, most definitely not. What many people don’t understand is that in order to get a good 3D / 4D ultrasound scan, one must first get a good 2D ultrasound scan. The gender is therefore always revealed on 2D ultrasound first before it is seen on a 3D / 4D ultrasound scan. A boy gender is generally easier to appreciate on a 3D / 4D ultrasound scan than a girl gender. The 3D / 4D ultrasound scan works on a method called surface rendering which displays the outside of a baby and is not like 2D ultrasound imaging which shows the inside of the baby’s body. The factors that influence getting a good 2D ultrasound scan also have an influence on getting a good 3D / 4D ultrasound image / video clip. These factors are things like enough fluid around the area of interest, the way the baby is lying etc.
