I'm afraid to say it, but that rapid color change looks fatal. Sorry to have to confirm you fear.
You are in Toledo area, your summers are relatively cool compared to the southeast, south and southwestern USA. I'm in the Chicago-Milwaukee area, with similar climate to yours. I found through this exact experience, that for me in my climate, it is best if I do not repot in spring. Cork bark JBP need a string of hot weather to "wake up" in spring. A couple weeks where daytime highs get into the upper 70's or low 80's F, which in my area sometimes does not happen until middle of June. I have learned that repotting in middle or late July through to about August 15 to have a higher survival rate, than repotting in "spring", because I never know when the trees will wake up. If I get a lot of east wind, the cold Lake Michigan water keeps me cool much later into the the spring than most people. I have had springs so cool from Lake Effect that my redbud would still be in bloom toward the middle or end of June.
So I let new growth, candles extend and leaf out, before repotting. July 15 to Aug 15 seems the best window. Usually Aug 1 to Aug 15. Note this is advise for fellow northerners, you all in Atlanta, stick to your spring repotting.
Also, these damn cork barks are fragile. If I know I am going to repot, I do no work on the tree for 6 months beforehand, and no work on the tree for 12 months afterwards.
Over the last 40 years, I have always had at least one cork bark JBP. The one that survived the longest for me lasted 18 years before I got too enthusiastic and worked it to death. At one time I had 15 cork barks, of 12 different varieties. Due to their fragility, and my slow learning curve I currently am down to just 4. This attrition is over a 10 year period, but I morn the passing of each.
