The fact is, " I did not typeset them, those files just were some sample files already being there." Yes, the output you have sent looks super good. I think this is not a good way of comparing outputs. We should have

a sample complex bidirectional text which contain everything in it (boxes, LTR and RTL texts, poems, colors, diagrams, footnotes and ...) and then compare the produced outputs. Please also note that I am using LaTeX not context.
