Thank you and my apologies. I should have read the pdf more carefully where the distinction between the training data and evaluation datasets is described

Our training set consists of a large set of high-resolution images collected from theInternet, which we downscale to a random size between 500 and 1000 pixels, and then randomlycrop to256×256. We evaluate on three diverse benchmark datasets collected independently ofour training set to demonstrate that our method generalizes beyond the training distribution: thewidely usedKodak[22] dataset (24 images), as well as theCLIC2020[43] testset (428 images), andDIV2K[2] validation set (100 images).
