I do not believe it is, at least not that I remember. The pitch ladder is adjustable in the settings.
From the Sport SX Pilots Guide;
6.3.3 Attitude Indicator/Artificial Horizon
Roll and pitch attitude information is displayed as a colored background on the EFIS. If attitude information is not available (such as when the AHRS is aligning), the background will be black.
The colored background uses the traditional blue to represent the sky. If the EFIS is equipped with synthetic vision, and it is on, the actual terrain will be shown, otherwise a flat-earth representation of the ground will be displayed in a brownish-green color. When the synthetic vision is showing the ground, the actual horizon is shown as a thick white line. Since the synthetic vision extends 10 miles in front of the airplane (and not to infinity), it is common for the horizon line to appear above the terrain when at higher altitudes.
