calibre is open source, you can either create a private fork, or submit changes.
Have a look to see if the triangles are in the <install>\app\resources\images folder, if they are, then you could override them with transparent triangles in <config>\calibre\resources\images.
Otherwise set the left and right margins to a small number - like 1.
Or revert to 3.48 and Hide the controls - then you'll have a minimalist viewer, with no arrows and a scroll bar.
