Depends on screen size.
A 65″ 4K screen is really poor DPI.
65″ 3840 x 2160 = 67.78 dpi, poorer than almost all 1990s CRTs!
Fine at family viewing distance with 1:27 movie like Ben Hur. Rubbish for reading glasses or normal text reading distance.
I may though have made some mistakes in the arithmetic. Certainly compared with 23″ 3840 x 2160 (AKA 4K) you'd need 10,852 x 6104 pixels, which I suppose might be called 11K.
23″ 3840 x 2160 = 191.56 dpi, not enough for HDPI setting.
65″ 7680 x 4320 = 135.56 dpi, typical 8K
65″ 10,852 x 6104 = 191.56 dpi dpi
So I think 16K would be about 15360 x 8640 = 271.13 dpi, good enough to turn off ClearType or similar.
480 dpi would allow HIDPI setting and need about 27192 x 15295 which marketing people might call 28K or 30K

Cinema has various different resolutions called 4K, 8K, 16K etc and the normal 4K, 8K 16K of domestic monitors are simply multiples of the 1920 x 1080 (HD or 2K) 2K may also refer to resolutions like 2048 × 1556 (full-aperture), 2048 × 1152 (HDTV, 16:9 aspect ratio) or 2048 × 872 pixels (Cinemascope, 2.35:1 aspect ratio).
There are 2560 x 1440 monitors. That should have been entry level HD. The 1440 x 720 is hardly HD and PCs often had 1600 x 1200 4:3 (common by 2002), till TV panels for 16:9 took over at 1920x 1080, few screens had 1920x1200.
4K = 3840 x 2160 (UHD or UHD-1)
8K = 7680×4320 (UHDTV-2)
There may not be a 16K spec.
