While there is definitely a reduction in fidelity, it also affects the aesthetic, and overall look of the game, which is where RAD's decision for The Order stems from. So while it is objectively worse in one way, it achieves the look they are going for that simply could not be done at a higher framerate.
And not really, because films don't look better at a lower resolution, and there's no standard for low resolution in film, but to that point, there's a reason some movies have very distinct colour grades to alter their picture (i.e. Green in the Matrix, Yellow in parts of Breaking Bad) it's not because they couldn't do it in regular colours, it's because they made a choice to convey their message in the best way. It's all about the aesthetic.
Also thanks for discussing this in such a cool manner
