More advanced image compression technology?

[MasterInQuestion]

    Do you have interest in deploying more advanced image compression technology?
    Currently I'm testing WebP Lossless, and received very promising result:
    https://github.com/MasterInQuestion/attach/commit/401c58fc3a56d265feadda567f02d79de93ff10c#r140161715

    And I believe lossy ≈ pre-filtered lossless.
    Also working on denoise techs yet:
    https://trac.ffmpeg.org/wiki/denoise

    I would like more feedback from actual data.
    Not looking for financial patronage.

    Extra note:

    "On-the-fly generated content cannot compete those generated without time/resource constraint."
    "Compression may also trade size for speed (useful for intermediate case) or vice versa (archive)."

    I believe the IIIF [ https://iiif.io/api/image ] framework maybe pointlessly eating a lot of server resource:
    Mostly may be alleviated to client-side.
