Could anyone please explain why this setting needs to be done via xrandr?

Why not via the xorg.conf.d files?

To enable the TearFree option for example you can add:

   Option "TearFree" "True"

inside a xorg.conf.d file for example.

So why can't the color range be set via a xorg.conf.d file like this for
example:

   Option "Broadcast RGB" "Limited"

?

Why xrandr and not xorg.conf.d? Or why not both?

Also, why is the AMD driver's option being called:

xrandr --output $OUTPUT --set output_csc tvrgb

?

For the Intel driver it's called:

xrandr --output $OUTPUT --set "Broadcast RGB" "Limited"

Why does the setting have to have a different name between the AMD and Intel
driver?

Why can't the names just be kept the same?

Regards
