Oh yes, it would be seriously dumb to leave such setting without a switch to enable/disable it. Forcing it / leaving it out totally is not the way you handle such features with multi-$$$$ camera body.

Thrice,
The difference becomes even more apparent when you compare histograms in Rawdigger. The 3.2 second exposures show a bi-modal distribution in all four channels, one grouping being darker and the other, smaller grouping consisting of these "hot pixels". It's easiest to see these using a logarithmic Y-axis scale since the hot pixels are few in number compared with the background.
The distribution changes at 4.0 second exposures. All the "hot pixels" are truncated. eg: ISO 6400 and ISO100 comparison with no LENR, no DRO, dark room, lens cap on, firmware 4.0:
My conditions: A7Rii, latest firmware (4.0), LENR on/off, DRO on/off, iso 100/6400, compressed raw vs uncompressed raw, 3.2 sec vs 4 sec exposures at f/4, 35mm (16-35 4), lens cap on in dark room.

So, did the firmware upgrade (fw 4.0) fixed the Star Eater issue for the A7RII or not?
Seems like they have modified rather than removed the filtering, with some improvement, but still some modification so not 'raw' raw. It's not ideal weather or moon phase here, so having to be patient.
