Undaunted I researched further.
I thought this thread looked promising


and I checked a few things out but I suspect it was written before 16.04.1
and .1 has corrected the bugs in part.  I noticed late it was for lubuntu
but guessed ubuntu was the same.

I am reading this at the moment
but again notice it predates 16.04

I have not ruled out it is something to do with my graphics card nvidea but
the upgrade appears to have installed the latest driver.

If I understand things correctly the boot sequence goes something like
GRUB opens the kernal using certain parameters.  The kernal(s) have been
pre-compiled during kernal updates and compilation includes ref to display
drivers so the screen post GRUB works.  If this limited understanding is
true, I am unclear when "plymouth" is called - prior to kernal opening I
guess.  If this is true, then "plymouth" can only display splash screen in
some form of monitor default mode.  But I am guessing.
Can anyone point me in the right direction to try and fix please.  I'm not
sure if it is still a formally recorded bug which I just need to await a
fix for.
