A display on a kitchen wall is read in passing, at distance, by somebody carrying something. That is a completely different problem from a phone held eighteen inches from your face, and scaling up the phone layout produces something that is large and still unreadable.
Fewer things, much larger
At eight feet the useful information budget is perhaps five items. Today's date, what is happening today, who is doing what, anything overdue, and anything wrong. A dashboard that shows twelve panels at distance shows none of them, because the eye cannot triage at that size and speed.
Contrast does the work that color usually does
Across a room, in variable kitchen lighting, subtle tonal differences vanish. Hierarchy has to come from size and weight, with a genuinely large step between levels — and the one saturated thing on the screen should be the thing that is wrong, because at that distance color is a signal you read before you read words.
And it should never need touching
A wall display that requires interaction to be useful is a bad wall display. It should be correct while nobody touches it, update itself, dim at night, and survive being ignored for a week.
