Most onscreen readouts are canon except when they contain information that blatantly contradicts everything else we see onscreen and is considered official by CBS and Paramount. Though Jonathan Archer's Starfleet bio file from the TOS-era Defiant in "In A Mirror Darkly, Part II(ENT)" was partially unseen it's pretty much accepted now that Archer went on to be elected one of the first Presidents of the Federation and that doesn't necessarily contradict him being called Admiral Archer by Kelvin Timeline Scotty.
