Unfortunately 4chan will mess with JPGs encoded with mozjpeg/jpegli so it's not possible to easily use them for a comparison here. Anyway for the purposes of gauging whether VMAF is of any use for image quality comparisons, specifically cartoon images, I HAVE to use libjpeg-turbo because mozjpeg/jpegli might have been tuned to cheat in VMAF. Similarly VMAF cannot be used with JXL/AVIF since they're guaranteed to cheat in them.

I'm doing all this shit because BOTH SSIM and PSNR failed to predict quality of cartoon images with BOTH Webp and JPG.
