I wouldn’t say captured in particular, any kind of modelling makes things a lot more flexible than before.
Honestly I can’t see there being that many new DO IT ALL 4 CHANNEL behemoth amps being released a la JVM or VH4. They are almost getting to the point of being an analog modelled - different amp circuits for different channels, complex fx routing if you want it.
I think it’s as much as the decline of people needing big amps for a lot of things as it is technology getting better. And it’s largely down to cost+ease of going on the road with something small and light vs having to travel with huge amps, which is literally going to be a deal breaker for many bands when trying to tour and not come out at a loss.
