As odd as I find the perspective, I just played the Grusin after the Evans and it’s clear how much more overtones it has and how much more vibrant the sound is compared to the vintage Evans recording.
It sounds as if Grusin’s piano cover was up while Evans’ was closed and sounds somehow damped in comparison. The Octave recording simply sounds as if played back with an omnidirectional speaker 
You have to go somewhere back in the room, then it sounds as a distant live piano filling the room. From the sweet spot, it’s too big and unfocused.
