It appears that certain lenses, particularly some of those with short flange distances, are likely to reflect the magnified pattern (maybe just a spectral part of it) back onto the sensor.

The RX1 sure doesn't seem to exhibit this aspect, and it also has a very short flange distance.

Did you try with a LED flashlight beam pointed into the lens over a dark room? With most cameras & lenses one can find at least traces of this phenomenon when trying hard enough. The intensity varies a lot though, with many cameras it is mostly not objectionable. Related real-life circumstances are sun-through-the-leaves, some sunsets, stage lights and such - generally not things one'd shoot every day. And I think problems are more likely at wider angles.
