So when I buy an OLED TV, does the store procure it for half the price from the distributor?
Generally yes.
can the distributor force them to keep prices up not to upset the other resellers?
Retailers upsetting other retailers is called channel conflict and is often solved with minimum advertised price policies. High-end companies like Apple and Sony often have this policy which is why you see the same price everywhere.
Also, the margin in Apple products for retailers is quite, quite low. I'd say 10% or less. That's why lots of "Apple authorized resellers" have either closed or expanded their business to accessories and services in the last 10 years.
Generally yes.
