We obviously know R2D2 doesn't have jaggies, but an algorithm like super resolution obviously doesn't. So taking the GOUT as a source it tries to enhance details including jaggies. Another filter might assume all edges are smooth, so it will correct the jaggies in R2D2, but also smooth sharp edges that are supposed to be sharp. In the end no filter will be able to perfectly reconstruct the true source material. A combination of methods could certainly do better, but there will always be some gains and some losses.
