The aircraft appears to be have been certificated for single crew operation, thus may not be a Part 25 aircraft.
For a Part 25 certification, or equivalent for IFR rated aircraft, I would expect that SV to meet the requirements of not displaying hazardous misleading information, and if applicable fitted with a comparator system with a greater availability than the display.
There is some information in CS 25, which appears to indicate that any synthetic vision display must meet the requirements of the host display - EFIS, HUD.
