1 – The default preset used is the Studio one and it remains the same unless changed to ArchVis. These presets do not affect the render quality presets.

The Revert to Default Render Settings button from the bottom of the Settings panel in the Asset Editor restores the settings preset chosen upfront by the command. 

In order to get proper results by the ArchVis preset, the Rhino Sun has to be turned on. You can do this through Asset Editor > Lights > Rhino Sun Document. The Revert to Default Render Settings button also turns the Sun on.
