That's why you should prefer LPIPS to PSNR. LPIPS is a learned metric that uses subjective human input.
That said, it's limited due to the training set, iirc. So we still use PSNR regularly — it's an easily-understood metric with widely-understood limitations, which is in practice not too bad. Devil you know, etc.
