Hi John,
The horizontal lines in the first picture are a known issue, as you said, black cal will remove them. It's in the pipeline to add correction for those so you don't need a black cal every time, but many other features are higher priority.
The dead pixels you're seeing appear to actually be on the image sensor. If you're OK waiting, we're going to add dead pixel correction, if they're really getting in the way right now you could send the camera back and we'll replace the image sensor at no charge.
The colored dots/bands are the RAM temperature issue, the new update coming in about a week will completely fix those.
David
