Actually no, my friend learned this the hard way during a photogrammetry project, he rented a photo studio, and made sure the background were perfectly black and took the photos but the photogrammetry program (Meshroom I think) was struggling to reconstruct the mesh. I did some research and I learned that it uses features in the background to help position itself to make the meshes. So he redid his tests outside with "messy" backgrounds and it worked much much better.

This was a few years ago so I don't know if things are different now.
