Bookeh COP just respects the layer's border settings

depending on what you want to affect you can either change those where the layer was created (File COP, Layer COP, ... )
or if those are set to default you can change Default Border settings on the COPnet

or just surgically use Layer Properties COP right before the Bookeh COP and change the border setting to Clamp or whatever you want

in H22.0.473 diving into SOP Create LOP or SOP Modify LOP still shows the LOP level camera with BG Image for me, even updates when animated

as for cameras imported as SOP level camera primitives, I don't think they support background images yet

here is a version that automatically figures out UDIMs, transforms to image space and outputs them

however, I'm not completely sure if there is something better than using @UDIM context option as I find it extremely unreliable in terms of updating when I switch the default UDIM, but with a bit of nudging it updates

also in this setup final ROP output correctly updated @UDIM per output only when I checked Compiled Cook, and I don't know the implications of that for copnet that is not compliable
