It looks like it came from the original DEM merge.
Re my own point 2:
I was playing around with the alpha value to overlay maps on top of the DEM,
which looks alright - except the default blue is a bit too 'strong', and thus
hard to make out map detail around the coasts. And since I live in Portsmouth
(UK), it's quite an obvious thing to look at!
Thus maybe change the default blue to a slightly lighter shade - 'light blue'
seems to work well.
Possibility could keep colour property; but make that apply to the sea level /
min elev colour.
