Samyang 14mm f/2.8 ED AS IF UMC dead pixels with Canon 7d mk2?

My better half went on another northern lights photo moment with her newest lens addition, the Samyang 14mm f/2.8 ED AS IF UMC. However, upon viewing the photos on the big monitor, we notice these "dead pixels"...

What is strange, is that on her other photos, photographed few moments later, the dead pixels aren't visible anymore...

What does this mean? Is the lens faulty or does the camera need service?

I have attached the ones where you can see the dead pixels and the one with no dead pixels.

Any thoughts and advises on this matter? Thanks in advance!

Canon EOS 7D Samyang 14mm F2.8 ED AS IF UMC / Rokinon 14mm F2.8 IF ED UMC
