arXiv 2608.05424 shows ImageNet- and LAION-scale pretrained encoders pick up metadata traces tied to camera and image-processing properties. Deliberately injecting metadata-semantics correlations during pretraining produces systematically higher metadata sensitivity and larger degradation under metadata distribution shift, and mitigation reduces sensitivity even to unseen metadata types without hurting downstream performance. The dual edge: this same sensitivity partly explains why encoders detect generated images, so removing it improves OOD generalization at a cost.
