PSNR SSIM not aligned with paper

Hi, for the synthetic defocus blur dataset, I use your pretrained results to calculate PSNR and SSIM. But my results are way lower than the results in the paper. Do you really use the synthetic_gt folder for GT evaluation? I use synthetic_gt for GT and evaluate defocusfactory1_full_woprior_wodepth/renderonly_test_199999 on 000/008/016/024/032 for factory scene.
