Your Nichia might survive. Djozz tortured one on copper to much higher currents.

So what is going on with the Nichia219 on copper?

I had high hopes for some improvement using the 219 on copper, but I did not get more than 1.3amps from a 18650 battery through the led, despite the use of a 2200mA Nanjg driver. Vestureofblood got a bit more from a 2800mA driver, but still under 2A. So despite of me not being an electronics expert, I did an attempt at testing the Nichia219 on a 16mm Sinkpad to see what is going wrong. And I must admit again (as in my recent MT-G2 measurements) that I did not do extensive measures to calibrate …
