I think size, field of view and viewing angles are other important considerations.If you buy a decent LCD with a VA panel they get pretty close.
In many ways I prefer my Sony XE90 and XF90 over my OLED.
Don't get me wrong, I can really appreciate what an OLED does well, those tricky scenes with dark and light at the same time, and I definitely think HDR is far better on OLED, but I could live without HDR and 90% of my viewing the Sony tends to look sharper, have better motion and just has a nicer image.
I wouldn't buy some LG IPS panel LCD though!
I bought one of the Samsung QLEDs before xmas, Q70, that was awful, blacks were far worse than my XE90, hence buying an XF90.
I got an XG first, but that was far worse than my XE, so returned it and picked up an XF90, which is exactly the same as the XE, just menus a bit quicker and it seems to go a bit brighter.
So I would happily live without an OLED.
In fact I will probably grab a Q9FN used when one pops up at the right price and give it a try, the one I saw looked great.
If you're sitting quite central viewing angles may not matter. But VA panels do suffer off axis.
Also if you're going 65" then 500 zones that a typical FALD set has start to look quite big in terms of controlling Halos and other artefacts. This is especially true if you're sitting close in order to be within the THX FOV.
