The olive knits on the L-2A jackets is interesting, and the photographic evidence is reassuring. I would only be able to add to speculation, so take these comments with a grain of salt. There could have been olive knit that the contractor attempted to overdye to blue, and if not done well that could cause the color to wash out over time and with use, and result in the base olive knit underneath. This is purely what-if based on speculation, but it would get the garments past the government inspector. Also the reason one can find some jackets with blue cuffs yet olive knit is because those are made differently; the cuffs are tubular and the waist and collar knit is not tubular. So, the contractor could have had olive knit for cuffs and waist/collar, ran out of the cuff knit or switched to blue before they had blue on hand for the waist and collar knits.
So I guess my mind is unchanged on the subject. We can speculate on but, as we have seen, such unvetted speculation in other circles becomes "must have beens" and has led to a lot of quotes of limited contracts, etc. from those who must know. If anyone can show me two or more untouched original jackets from the same contract run with these "expedient" factory knit variants I might tend to say it was likely. Any I see will be assumed to have replacements knits or be some sort or a repro.
That's just me.

If knits on L2-a’s were being replaced on jackets 2 or 3 years old then either there were some very poor quality knits around, especially as we’re seeing collar and waist band knits all replaced.
With all due respect...the first jet Aces ( not wearing A-2’s) were Walter Nowotny and Walter Schuck...flying on several Me262 jet variants..plus others...(https://en.m.wikipedia.org/wiki/Walter_Nowotny)One thing I've always liked seeing are A-2 jackets in Korean War service. And something that many forget, the first jet ace achieved it wearing his trusty old A-2 and not a nylon jacket

Walter Nowotny had no chance to wear an A-2, nor a nylon jacket. Walter Schuck, whom I had the great honor and priviledge meeting during a reunion in the US, wore honorably several allied flight jackets.
OK, accepted..Sorry Pilot I was sloppy writing that and should have qualified that with, the world's first jet versus jet ace wore an A-2.
