I knew the 8K units were a gimmick from the beginning! NOTHING will beat NATIVE resolution even at lower pixel count. Any resolution outside the native resolution of ANY display will look bad regardless of how high the display resolution is.
You can test this out yourself! Just try any 4k computer monitor and set it to 1440p, then look at a native 1440p monitor. The lower resolution native 1440p monitor will look FAR superior.
Nothing can beat native resolution…nothing. The 5K+ is the unit to buy by far.
