Pik was designed initially without quality options only to do the best there is to achieve distance 1.0.

We kept a lot of focus on visually lossless and I didn't want to add format features which would add complexity but not help at high quality settings.

In addition to modeling features, the context modeling and efficiency of entropy coding is critical at high quality. I consider AVIFs entropy coding ill-suited for high quality or lossless photography.
