An exemplary data precision preservation system divides a depth representation into a first section and a second section separate from the first section. The system determines data bits representing numbers that correspond to a lowest non-null depth value and a highest non-null depth value represented in the first section, and converts an original set of depth values represented in the first section to a compressed set of depth values normalized based on the lowest and highest non-null depth values represented in the first section. The system then generates a dataset that includes data representative of the compressed set of depth values and an inverse view-projection transform that is based on the lowest and highest non-null depth values represented in the first section and is configured to facilitate conversion of the compressed set of depth values back to the original set of depth values. Corresponding systems and methods are also disclosed.
