Attached a few clips showing before and after color correction comparisons of a couple of 4k clips filmed in 4K 30p 10 bit and 4K 60p 8bit during our trip to Fiji.
Color Correction was done with the Color Finale Plugin for FCPX. Only simple correction of color channels, plus exposure and saturation correction. A bit of hue fixing here and there to get the blue right, but no sophisticated grading.
I may do something similar using Davinci Resolve 14 if I find the time
