JEEEESUS christ so after 10+ attempts I finally got a similar VMAF score to a Q20 Webp.

24.6 KB webp divided by 62 KB libjpeg-turbo = 0.4 so Webp achieves 60% better compression efficiency than libjpeg-turbo.

I'm not sure if this sub-90 VMAF scores works similar to SSIM to denote low quality but it does seem like it.
