No, I don't. I thought the discoloration would eventually disappear as the plant grew, but it didn't. On the worst cases, where the spots developed black spots or the surface skin developed some necrosis they behaved like all those kinds of injuries and made permanent surface scars. Some of the necrotic tissue was the result of the insecticidal soap. Some plants seemed sensitive to it where others didn't react to it. The worst was a hybrid opuntia which I learned quickly I needed to rinse off the residue. The Echinocactus grusonii also was sensitive. That opuntia is a diva of a plant anyway, as it turns out
. Some of the other small barrels didn't react at all as far I could tell. The problem with using it was that it needs to be used when you see the bugs. They are very mobile and very alert to danger to themselves. They will fly off if they feel threatened. The plant in your photo has a lot of smooth skin, so applying anything in the way of a contact spray residute might need to be rinsed off asap. The discoloration or scars won't grow larger, so as the plant grows they take up an ever smaller percentage of the surface. In that sense they recede, but the yellow never returned to being green.
Good luck. You may have something entirely different going on. You'll just have to watch the plant for a while. I'm not sure what else might cause the effect. Light, water, nutrients are all always something to consider. Sometimes plants just react to a change in location and throw a tantrum.
