Maybe this could help you understand what BMX is talking about:
In other words, at 12 ft from the display, you'd start to see some benefit going to 4k at about 85" diagonal TV screens or larger.

Short version: OLED has better picture, but LCD is cheaper, much brighter (very useful for HDR), No risk of permanent burn-in, but viewing angles aren't as good as Oled.

At your fairly modest 2k budget you must choose your own priorities and make some sacrifices.
