Experiment: 512-res generation + SeedVR2 upscaling matches 2048 output

A Reddit user found that an image generated at 2048 resolution, downscaled to 512 and upscaled back with SeedVR2, is virtually identical to the original. This suggests high-resolution models may be unnecessary if VAE is detailed enough. However, most current models' VAEs distort details at 512.
