And I don't want a definition for "4k DCI" or "4k UHD" .. just a formally accepted definition of "4k" (in the context of a display resolution). We can all agree that it colloquially means the number 4000, I hope.
There is not one definition, if you hear “4K” you can use the context of the conversation to determine if they’re talking about the consumer 4K UHD format or cinematic 4K, neither of which have a vertical resolution of exactly 4000px.
UHD standards are maintained by ITU
DCI standards were developed by the DCI group and are now maintained by SMPTE

I agree. But then it's not a formal standard.
