And for you, color perception is important, no?

Up to a point, the visual system's chromatic adaptation still keeps white objects perceived as white though with a new IOL the change will be very noticeable. This system is very effective in preventing a substantial amount illuminant metamerism. There are many types of processing shenanigans that go on like the Stiles -Crawford effect, using blue cones mostly as a color guide and not resolution due to chromatic aberration, neural sharpening and edge enhancement etc. Nature predated Photoshop. The visual system is not a camera.

So far my vision seems to still follow the 2 images I first posted. I have some blue block computer glasses, that used to look clear, but now I see their yellow tint. The yellow tint when wearing them matches what my vision was like before surgery. I showed the glasses to a friend who also thinks they are clear. I suggested he get his eyes checked.

Are you saying my color vision will start to change/adapt over time now? Lights in the house also seem more white than before?

One thing surgery has done, I no longer argue with my wife over the color of some things :-)

For a while I held Moose's view - to keep upgrading my glasses and postpone surgery as long as possible. I had no idea how much blue color I was missing. I guess with B&W photography, no problem, but for color photography... My blue cones are now getting a new life. And probably why things look brighter.

I wonder if this explains the blue and black dress phenomenon?
