Im 99.9% sure that what you like about the sound are the early room reflections (and how they interact with the instruments own resonances). "The room is part of the instrument". Personally, I get very close to this with the more nonlinear presets of MSoundFactory (e.g. Cookies & Milk, Powerhall), with a strong bias towards early reflections and very short decay times. You may want an aggressive lowpass so that it sounds like a growl moreso than a reverb.
And don't forget to add saturation, tube and/or tape .
I'm also currently experimenting with feeding the resonance signal back as an put into Pianoteq to get some of that interaction between the room and the instrument, but haven't quite hit the sweet spot yet (hard to dial in).
I've played with physically modeled resonators like ObjecQ, but found that they didn't add much
Hammer noise is a significant component, too, give that a boost.
If you have note edit I'm pretty sure you can get any character you like out of the bass notes by boosting the higher partials, but I don't have any concrete pointers to give there (need to experiment more)
PS: Also let's not forget that this is a promotional vid by Kawai so you can be sure the recording has been "photoshopped" to a high sheen - I wouldn't expect this to be a raw take straight from the mics
