Interesting that vein area is something to look for.
So the question would be whether the vane area is similar or not in the most-often-recommended E39 replacement rotors:

Most often recommended replacement rotors:
- ATE solid (Premium One brand is OEM?)
- Balo (which model?)
- Brembo solid (which model?)
- Centric Premium ?model
- Zimmermann ?model

BTW, over in this thread today:
- Yet another rotors/pad question
A reference was made to a nice treatise of drilled vs slotted vs solid rotors (although this thread is only about OEM-equivalent rotors):
