Yes, that certainly could be true. But would a pilot typically keep his collar under the harness? That does not seem very comfortable.
Do we have a copy of the A-1 specification? The 37J1 specification 3.(e) says: "Wristlets, collar, and bottom of jacket shall be a closely knitted wool worsted." Nothing about ribbing there. Ribbing makes sense at the wrists and the bottom of the jacket, but the case for the collar is less compelling. Later jackets like the A-2 and M-422 did not have collars that stretched. Perhaps there was a later revision to the A-1 specification that required ribbing but the early spec was similar to 37J1. There is more variation in the design of the A-1 than the A-2 so differences like this are plausible. The only A-1 collars that look felted to me have visible edge stitching and a D-shaped (rather than closed/circular) button loop.
Perhaps the resolution on this photo is just not high enough, but:

If you zoom in on this Doolittle image, the collar looks the same, appears to resemble fleece.
