Your 3D capture contributes capturing a moment in time.
No 3D scan is redundant even if its of the same location or asset because each scan was very likely taken at a different point in time. Your 3D scan captures the state of that asset at the time of the capture which will likely be different from previous and future scans.
With each 3d scan you help build a better copy of reality. Since 'Truth" reflects the consensus of the majority, the more captured data of the same location, the higher the level of truth that can be attain about the physical world.
