Interesting about your colour perception being improved. It will be interesting to see what happens with my left eye since, ever since I started using telescopes and binoculars, I've noticed that when I used it on emission nebulas, it was like having half a broad band LPR filter in it, compared to the view in my right eye.

The natural lens yellows as it ages filters out the blue /violet end of the spectrum . The blue/blocking lens replacement has a 10% light transmission at 405nm similar to the aged eye . Cataracts are particularly yellow orange in colour . Even with a single lens replacement with a clear lens , my perception of blue light with both eyes open improved dramatically and whites looked really white . And there was certainly a big difference when looking through a telescope at M42 Orion nebula for example .
