I looked up the part number of the Bosch litronic and it matched with the same $$$$ ones that you get from the Porsche dealerships. (Of course I can't find it now).
The amazon description gives you almost no details but it does contain the following part numbers:
Brand Bosch
Item model number 302473374
Manufacturer Part Number 302473374
ABPA Partslink Number 0302473374
And it does say "Right -Bosch - HID"
And there is a separate entry for the clear Bosch halogen headlamp assemblies.
If I find the link that shows these headlights at the more expensive price mapping to the same part number on the Amazon page I'll share it here.

Edit: if it was me I would buy the Bosch because that is the OEM manufacturer, and especially since you are getting only one you would want it to match the other one
