Maybe the gap isn't as huge as you think.
Question: In what way would a hi-res color screen convey more information to the user of a DMM?
Cellphones these days have apps and need to adapt the user interface to anything a programmer can imagine. Not so DMMs. They display a single number (sometimes two), have no installable apps and do all their interaction with a dial and two pointy cables.
Given the long list of downsides to those screen (listed above), why would you expect a color screen to sell big enough numbers for a manufacturer to bother making one?

A graphic screen is much more flexible than a 7 segment LCD, some meters do use that flexibility (Like Fluke 289, Uni-T UT181A, Chauvin Arnoux CA 5293).
I like these meters, but in many cases the 7 segment LCD is much more practical and shows enough.
Kleinstein:
Graphics LCD can be nice if more than just numbes are displayed, like more complicated units ( e.g. kOhms, µS, °C, µs). Individual symbols get quite small and the 15 segment alphanumericals are not so readable for special characters. I don't think there are combined character / graphics LCDs. At least I have not seen them. A more variable display may help showing less digits large or more (e.g. 2 readings or frequency with higher resolution) a little smaller.
Not sure why one would need color - colored backlight may be enough, though not very visible in bright light. Anyway in bright light the simple 7 seg. LCDs are hard to beat - maybe a meter with e-ink display ?
If really more information (e.g. trand chart) is needed a BT link to a smart phone would be an option.
luma:
I feel like I'm taking crazy pills and forced to describe why the literal entire world has moved to color LCDs, along with every other category of test measurement equipment out there

There's plenty of those:
