Best Imac Monitor Display Color Profile for Editing FCPX?

Hello,

I'm hoping to find out if someone could recommend what the best display color profile is on my (iMac (Retina 5K, 27-inch, Late 2015)) Imac for working in Final Cut Pro X?. This is something I did not pay attention to, now I have the Imac calibrated but perhaps there is a better color display profile to use with FCPX? I could be off on my color correction when I just eyeball it, but yes I do also use the RGB parade and Luma waveforms in FCPX color correction.

Thank you for your suggestions!
