Nathan, I think Geoff's analysis is correct. I don't think this is the
"banding" that most people refer to. I have gotten those on the M8 as well,
for example, a purple band of light where there's a specular light source.

One thing to remember is that even when shooting RAW, the CPU is doing a lot
of interpolation. There is always a chance that some boundary conditions
would cause a bug to show up. If your condition is becoming repeatable, it
could even be some hardware defects that are showing up in the circuitry,
combined with certain operating conditions that cause the problems you see.

As for fragility of a brand/camera, electronics changes everything.
Supposedly the Canon 1Ds Mark-whatever never resolved their autofocus
problems etc. I think the difference is that people do expect a higher level
of reliability and performance due to the price, but in reality, it isn't
always true.
