I think also that 1 pt, inch cm, ... shall have the physical wanted size. Your unrealistic demand what made unrealistic by people and companies which ignore all about others. the web developper which mean that all must be expressed in pixel, Microsoft,..., Apple which decided that a new inch has a size of 72/96 on the display in order to render wrong web page correctly. 1) The OS can read the display EDID and assume according the the vertical and horizontal size the type of display, but this can't be perfect. The type of display and accordingly the viewing distance may be dependant of the screen width/height as reported by EDID, what is the width/height for which the device shall be considered as a tv (large distance or tablet (low distance) ? 2) This may be reported by X which can report the physical size of the display with an accuracy of +/- 5 mm if the EDID are taken into account. 3) Not only text size but also pictures sizes.
An other point which has to be taken into account and wihch is always ignored idt the width of a text area. In order to allow a good readability the width shall not be larger as approx 20 cm (~ 8 inch) for a typical viewing distance of ~60 cm / ~30 inch on a computer display.
