Update: Hah, turns out although I had calibrated my monitor I'd disabled the config in the Spyder app for some reason!
I've bumped the contrast up a bit and tried to bring up the detail in the eye a little more.
I think this looks better without pushing the edit too far?

This would be helped by increasing the contrast and upping the gamma a bit. It may be my monitor, I haven't calibrated it in a couple of months.
