Yes, since the last couple of years. I tend to help architect and scaffold large projects that goes on for years, and changes a lot of developers, designers in its lifecycle. I was pretty confident of moving to OKLCH about 4-years ago and have have had it as default. OKLCH values are now the source of truth for these projects, and other design elements — all the way to Powerpoints (HEX/RGB) and Print (CMYK) are derived from OKLCH. There are variations but most people don’t even know the difference.

This started way back working with my long-term business partner and he built a pretty good tool to help visualize and tinker with it.
