Will the W+ vector affect the reconstruction quality?

"Thank you for your work and response.

If I input the face segmentation mask obtained from a wild image processed by a segmentation model into e4e to get W+, it might improve the editing effect. However, does W+ itself carry other image information? For example, does the W+ vector obtained from the mask affect the image reconstruction quality? Does the reconstruction effect of diffusion models rely solely on VAE?"
