Have no idea. I reckon it's in an industry insider pdf somewhere. Sort of like how the pdf of all the marker bindings is leaked somewhere:Is this information available? Where can I find it? Asking for ski boots, by the way.
The specs for race boots, this head model for example, says what last number it is on the head website. But no mention if this is a new last or same last as previous season. It would be useful for someone who bought last season's or two season's ago's 96 last, for example, to know that the current 96 last is the same. That way, they can just buy the new model online, knowing it would fit more or less the same as it used the same 96 last.
RAPTOR WCR 140S
The Raptor WCR 140S has a new level of absorption capabilities. With a 96-mm last and Race Balance, this boot allows skiers to remain centered and recover easier.

I think it would just come down to experience and fitting the boots and getting a feel for what feels good on your feet. Then cross check that feel with the last number.
Also, although different manufacturers use different lasts molds and may also use different molds even with the same last number within the same manufacturer (new mold for new season for example), I think they more or less coalesce to the same measurements. This is just my guess. The reason being they probably use the same database of average feet measurements. Also lots of copying in the industry. Let's take high volume boots. The day one boot manufacturer came out with the first high volume boots, the other manufacturers wouldn't want to miss out on the new market and produced their own, but probably using the same database. It's just a matter of one manufacturer having a bit wider forefoot or higher instep or tighter heel, but the shape of the 102 lasts, for example are more or less the same.
