Well, I wonder about memories and associations formed around colors. After reading the article I was passing a tree lined street, thinking of what green has meant to me over more than 3 decades. What if it's not "real" green? What if it changed some day?
Also, I don't know, some people seem content with flawed senses. Eg. A lot of people with glasses seem to shrug it off and accept it. It doesn't cause them existential crisis. And that is a much more practically troubling problem than color blindness.
I personally think you should be not affraid, the time to get used to things is mostly not long. See it as an enrichment similar to "I am used to see VHS video and now I am looking at the rich details and colors of Blueray". The experiences stored inside you concerning your lack of vision will in part stay and some of it that is not important for the function of your system later on will be lost.
It is as real as any approximation to the full spectrum of light can be. But it provides less information about said distribution to you than for trichromats. I can't really understand your feelings, because I will go for near-infrared sensitive cells in my retina when/if the procedure will be feasible and if/when four-color displays and cameras will appear.
