Adobe's bundled profile for A7r-II and also for say Pentax 645z (which has virtually identical color response, could be the exact same CFA) is deliberately desaturated in look.
Sony's sensors have strongly overlapping color filters, and separating them (=increasing saturation) means quite aggressive matrix weights with strong negative factors which make the profile less robust in extreme ranges (triggered by some artificial lights and such).
There are other ways though, I've generated profiles both for the A7r-II and the Pentax 645z and as long as you limit the blue channel a bit (render blue colors light) you can still get pretty robust behavior despite having realistic saturation.
