I think the answer is:
Only S&W knows for sure, and they ain't tellin'.
Seriously, I'd like to know also. But the only thing available is speculation, even if it is informed speculation.

I agree, and asked this same question on the forum within the last year, and got no definitive answers. For example, on a Model 64 and Model 66 made the same day, are the frames and cylinders heat treated differently? If different, then it would seem they loose manufacturing effeciencies. If the same, then why is one OK to shoot .357 magnum and the other supposedly not safe (as per the factory) for .38 Special +P+.
How about a Model 60 no dash and a Model 940, both made before the magnum frame, why is one safe for high pressure 9mm and the other supposedly not safe for .38 Special +P?
Within the family of K frames, does S&W 'engineer them down' specifically only for the caliber shown on the barrel? A .38 Special K frame safe only for .38 Special, and a .32 caliber K frame made weaker on purpose, and a .22 caliber K frame weaker still?

I used to know someone inside the Springfield plant and was told that both cylinders and frames get different HT. So, you can't just hotrod a Model 64 cylinder or frame for .357 (or a 625 frame for .44 Mag-level loads).
