ai image and 32-bit displacement

I needed a way to let Arnold GPU know which UV set to use for the textures, displacement which span across 9 UDIM tiles, and which UV set for Xgen's mask (uses a single tile) made using PaintEffects. So I used Arnold's file node ai image and assigned the UVset name. However for 32-bit displacements which are EXRs file format I am not sure what the Wrap Mode should be. Reading the Arnold documenation there is a mention to use "File" as the wrap mode for OpenEXRs. For test, I tried using Mirror Wrap Mode to see if it makes any difference. I could not notice any difference.

Anybody know if it makes any difference, or what the actual settings should be when using displacements + ai image node?
