No worries lol Simple truth TV manufacturers screwed up the standards with the not 4k; UHD resolution. 4000 or 4096 is 4k. They should have stuck with the #p at 16:9 standard since 1080p is not 2k & was never marketed as such.
The only proper use of the k standard is Qhd which is a true 2.5k. Its also why alot of folks are confused & think 1080p (Fhd) is 1k when in truth it's slightly less tgan 2k (2000 or 2048). When in truth 720p (HD) is just over 1k.
In reality 8k Uhd is not even close to 8k it is more like 7.5k ish & doubling that 15.2k will be called 16k.
So really if we use the corrupted standard it is simple to describe as 8k half height. Which is how they used to describe hard drives at 5.25" that occupied 1 5.25" slot was half height. Or 2160p @ 32:9.
Even displays using different aspect ratios seem to each be calling it different things. In one sense maybe best to use MP to describe res realstate.
My phone for example if you use the nonsense approach of rounding is 3k (2880*1440) but then so is the Vive/Oddessy with (2880*1600) lol
The simplest truth read & understand specs instead of marketing hype.
