You can only get the best detail in the lightest tones by going back to a raw file and working carefully in the raw processor, and depending on the exposure, it may not be possible to bring out detail.
Was it a raw file (I assume so with a 1DX!), and what raw processor?
I have some information on bringing out detail in whites in a tutorial in Educational Resources. But that may not be relevant to this particular image -- I can't tell by just looking at it.
