The key and correct point is your first one - OBs sell
only Omegas, no other watch brands.
You second point is incorrect - all OBs are not all owned by Omega. Some OBs are franchised just like McDonalds - McDonalds do not own every McDonalds restaurant. For example, in separate physical locations within the Wynn hotel complex in Las Vegas you will find a Watches of Switzerland Store (an AD) and an Omega boutique (an OB). However, the Watches of Switzerland company actually operate both of them.
EDIT: Here's a link to an article to support the point I’m making above about WoS operating a stand-alone OB (see first paragraph, and also scroll down the article to the photo of the OB itself - it’s the second to last photo in the article):

Your third point is also incorrect. Real OBs will give discounts in some situations, I know because I got one. And to show that I really do know what an OB is:
