Just done a long exposure with the lens cap on and it's rediculas how many coloured pixels show. Green, blue, red & white. Fully zoomed in and there is atleast 3 where ever I'm zoomed in on the picture.
If I stay zoomed in on a red dot for example in one spot and scroll to the next picture - depending on the colours in the picture it's still there, especially in dark colours, but in some colours were you should still be able to see it, it's totally vanished.
Iv chose to clean the shutter on the menu and taken the same photo again with the lens cap on but it's no different.
Looks like Iv had it a while but only noticed it since taking these night shots - first time with this 5dii

A friend thinks there "stuck" pixels that can be removed rather than "dead" pixels.
