All one can really say is that the getter is doing its job.

I would think that if the vacuum had been lost the getter would've gone completely off and filament probably blown. It either has a leak, or it doesn't.

There's some getter material out there that doesn't go white when it's exposed to air. I don't know what it is.

I broke a tube once and it did not go white. The pics were posted on AA.

As an experiment, I left the flashed portion of the tube sitting in a dish for months. It remained silver. It never changed.

I recently broke a tube and again, the flash did not turn.

  Now that you mention it I recall those pics you posted.
  
  I wonder if it was somehow defective, or something different as you suggested?
