Obviously not. Some filters are very well known for their sound. The
Moog filters for instance.
Here is soemthing from Analogue Systems UK that sums it up:
"Moog's filter used a circuit called a ladder network. In
itself, there is nothing special about this, and many other
filter designs are capable of emulating its response. However,
Moog's circuit was flawed because it exhibited a small amount
of distortion. Many engineers would have sought to correct this
but Moog did not, perhaps because he recognised that the sound
was musically pleasing. Indeed, if a synthesiser sounds like a
Minimoog, it is called "warm" or "creamy". If it does not it
will often be referred to as "thin" or "uninspiring"."
The same can be applied to any audio hardware referred-to as
'vintage'. They all have characteristics. The best emulations are
trying to replicate these characteristics.
Don't forget to mention that the Moog filter also provide attack and
release times. A feature that isn't provided by all the mixing consoles
from the vendors you already mentioned. Why is this missing? Perhaps
Moog filters are used to produce sound, while mixing console filters
are used to mix sound.
