Canon 5dMk 4 - ISO 32k/ 30s - red/pink streaks normal?

Hello all - I recently moved from 7D to 5D M4 and doing tests for hot pixels.

on my 7D at 6200 ISO, there were few bright pixels but the overall canvass was black. This was taken with lens cap and viewfinder covered.

Similar test on Mk4 - I still see 3/4 bright pixels but the overall picture is full of pinkish spots.  I tried on manual and Bulb modes and same result.

is that due to High ISO? or is there anything wrong with the sensor? Please advise.

thank you.
