If you pixel peep that could possibly be chromatic aberration elsewhere also, under his ring finger, under his chin, in the water. Just a possibility to try lens correction for CA and see if it reduces. Otherwise it is fixable, patch tool or healing brush with the pic zoomed in a lot.
I thought of CA and tried to correct it with the RAW file, but that did not improve it. I have fixed it using the tools. But I'm still curious about the cause.
