"Only the M-bands were used to make the images you have seen (band 5/4/3
red/green/blue)."
And, he also stresses that it is indeed too early to conclude on the

"It's too early to draw any conclusions from these very early images.
Calibration of the visible bands is not yet stable. There is a lot of
work still to be done."
So I will calm down. ;-)
But still would like to better understand the issue of cross-talk on VIIRS.
