Last year I left Lightroom for Photos, which is surprisingly powerful when used with 3rd-party apps and extensions³.

In hindsight I probably should have contacted my credit card provider, but I guess I naively thought Apple would do the right thing. No such luck.
I can’t remember if it was specific to Aperture only or if it went along with other Apple “pro” apps.
It didn’t dim and desaturate standard elements though - it was a framework offering a set of custom controls that had their own art. That art was drawn to look similar to desaturated versions of standard controls.
