I can understand that actually, I don't think 8k at 55" makes much sense for TV content since you can't see the difference between 4k and 8k at normal tv distance when the screen is so small.
It makes a ton of sense as a retina-resolution monitor though! I half suspect that was the plan for the panel, and that some other market factor caused it to end up in a small run of surprisingly cheap TV's instead.
