Jazz at the Pawnshop in DSD 256

I see a new DSD 256 version of Jazz at the Pawnshop popped up at Acoustic sounds not long after I bought the DSD128 version. But they don't have any description of which equipment was used to make it. Only up to DSD128. Does anyone know if they just up sampled the 128 version, or they made a new fresh version for 256?

Edit: Just realized it's Jazz at the Pawnshop "Late night" But still would be nice to know how the DSD256 version was made.
