I've observed that the HSL filter within Substance Painter doesn't shift hues as well as OKlab does, particularly with regard to human perception of lightness. I've seen an implementation of this being used within a shader and hope to see OKlab implemented as an additional option within Substance Painter for the HSL filter. There is a possibility that better options than OKlab exist—please forgive my ignorance.
Side note: While you may achieve better results by adjusting individual layers for hue, along with the necessary manual adjustments for lightness, an improved HSL filter with OKlab would be a great addition for quick iteration or testing.
