You might be right. To be honest I thought the same. However many of B&W images indicate the prop center could be painted. What is more, most of pictures that show French F4U-7/AU-1 at the early service with the prop hubs and the caps there solid coated with the Sea Blue. The French sources suggest these prop caps of a Light Blue, Red and just the White depending on a squadron or Flottile. There was only one shot I've seen, with the prop center that looked like bing of the NMF entirely. Here a couple of shots with the coat tone seen ... please pay your attention to the first shot below. The difference between the NMF of the prop hub and the tone of the prop cap can be noticed exactly.
Also I found a couple of colour images that reveal tha the prop center was of white undobtedly. In addition I would like to make a focus on the white numbers on the fuselages and wings that peeled off at many areas what might indicate not too very good quality of the paint. And this is the reason that let me believe the prop center was of white that peeled off.
