Using default checkpoints. PSNR/SSIM usually improve until the 4-th step. Is it normal that images only deteriorate subjectively after the 1-st iteration and never improve?

Examples: img_002_SRF_2_HR_1 img_002_SRF_2_HR_2 img_002_SRF_2_HR_3 img_002_SRF_2_HR_4 img_002_SRF_2_HR_5 img_002_SRF_2_HR_6 img_002_SRF_2_HR_7
