Hasn't this exactly what LeCroy has been doing on their lower end parts for a decade or so? Surprised they didn't change the color of the UI to match their other stuff a little closer, but not surprised at all that it's happened.
Also don't think it's a medium range design, and don't think that it's particularly unreasonable. I've only ever seen up to 6.5 digit meters from Chinese companies, not 7.5+, and the build quality and performance seem to be solid. While LeCroy is predictably upselling it, so their model is a worse value than Siglent's, it's still right around the ballpark of the Keysight comparable meters, and specs and performance are again comparable.
They're filling out their product line so that a company or research institution can talk to them about a bulk order and they can say "we can meet all your needs!", and they've been doing that for a while. When was the last time LeCroy designed a DMM in house? Have they ever?
