The Case Against OLED
First of all, let's just get out of the way that OLED is better quality than LED or QLED. The problem with OLED isn't with quality, but with price. I would like to look at some examples of potential TV buyers and see where OLED makes sense and where does consumer logic break down.
Example Buyer #1: The Super Rich Guy/Gal
In this example the buyer could afford any TV they want, but most of the buyers in this category would probably have a dedicated theater room. As far as I can tell the largest OLED TV you can possibly buy is 97" and it's $25,000. At that price you'd be much better off getting a projection system for your home theater room and using an acoustically transparent screen etc. I could see where a super rich person might buy an OLED TV for a bedroom or for their super expensive condo or apartment, but that's it.
Example Buyer #2: The Upper-Middle Class Person
In this example the buyer probably has a large enough living room to accommodate up to a 100" TV, but does not have a dedicated theater room. Unfortunately, an OLED above 77" would be out of the question for this buyer due to the $25,000 price tag. Going down to 77" they can get an OLED for about $2,000. However, if you go to QLED you can get an 85" TV for under 1K and a very highly rated QLED for about $2,000.
Example Buyer #3: A Strapped-For-Cash Enthusiast
This buyer would want the best quality TV they can afford and it's hard to believe that OLED could fit that bill unless they really don't care about screed size or they have a small living room, which, admittedly, could be the case for some. Going from OLED to QLED is going to give them a significantly larger screen and more and better features (such as gaming features, connections, Smart functionality, etc.) for the price.
***Tertiary Considerations: Non-enthusiasts, such as friends, girlfriends/wives, in-laws, neighbors, etc. are much more likely to be impressed by a larger TV than a smaller one regardless of panel quality. People tend to want to hang out and watch the game or the movie at the person's house with the largest living room and the largest TV, so potential for more interactions and usage.
The Buyer's Dilemma/Potential Mistake
I feel like a lot of people are in this position where they buy 55" or 65" OLED where they could have afforded a 75" or 85" QLED instead. They get lured in by the panel quality and forget about size. They let perceived sophistication obstruct their better judgement. One of my good friends has a 65" OLED in a living room that is smaller and attached to the kitchen/dining room area. It looks great and is about the correct size for that area, but if he had a larger living room there is no way I would want to watch a 65" OLED over an 85" LED TV.
IMHO it makes sense to get the biggest and best TV your room size can handle. Size being more important than panel quality, at least within reasonable quality standards.
Thoughts?
Edit: The price for an 83" OLED is only $4,000. I didn't see that as I had a radio button selected for 85" and since OLED TVs generally come in 77" and 83" instead of 75 and 85 I didn't see the 83" TV option. That being said, a top-tier 85" QLED TV with the latest features and connections is still $1,300 than the cheapest 83" OLED TV. That makes is 33% more expensive, 2" smaller, and with potentially fewer features.
My opinion in summary: OLED TVs are better picture quality than the competition, but at a higher price. If price is no option or the room is small enough I think OLED makes sense. For my tastes (and my large living room) QLED is a better balance of cost to performance allowing me to get the biggest TV possible.
OLED: Better Contrast
QLED: Lager Screen and Better Features For The Cost, Brighter Screen For Brighter Rooms And Fewer Reflections
