This fills the gap between the rear window and the trunk lid.
How about the TRD style lip spoilers?

The window filler probably doesnt do much. Might reduce a little drag but doubting it. I would ventue and say it is cosmetic.
Lip spoilers work well. It will make more downforce than wingless/spoilerless trunk. It will make less downforce than a proper wing. It should also have less drag that both wingless truck and a proper wing.
Sorry I missed this question until now.
