The Rigol screenshots looks good from far, but far from good, it is breaking some conventions, like there's no need for the orange text*, it should (if needed) be exactly the same as everything else, because orange sticks out for no reason, it's not a selected item. The text sizes seem unnatural, like the digits 1-4 for the channels, only needed to be slightly larger than the remainder text, and not massively larger, and large+bold combined just feels wrong!
Now that things like custom zoom windows are becoming popular with 12-bit 'scopes, I've noticed some of the same problems regarding quickly identifying the division values. My older 'scope didn't need that since it had no similar zoom windows. And it's especially harder on those without the same 'scope, because you don't want others to waste time scanning all the periphery only to find that information isn't there.
Even though the larger-screen MXO 4 is ordinarily clear to read with very little clutter, when zoom windows are added based on user-defined window sizes (i.e. a dragged custom rectangle) then it can for sure take some mental time to figure out what the scales are. I've taken to manually post-annotating, since then I can make it as clear as I can, or bring things to attention with an arrow etc.
The instrument internally supports annotations, but I prefer some consistent shapes/styles, so I prefer to do it myself in PowerPoint etc. Helps others because they can see the annotations have whatever context you wish to include. I did the same with older 'scopes, i.e. glue a 'scope trace in a lab book, and draw arrows etc manually.
But many people just dump 'scope traces with no markup : (
Maybe instrument built-in preset annotations for time/div and volts/div could be useful though, i.e. allow the user to drag-and-drop the annotations in a clear part of the display, or in a single inset box just listing both of these, e.g. "75 mV/div, 1.16 ns/div". I might raise it as a feature request for MXO anyway, in case it gets taken up.
* Also, H,A,D,T feel meaningless. Takes longer to interpret them as Horizontal, Acquisition, etc., than if they were totally omitted and people could see the meaning from the units alone (e.g. ns/div etc) or smaller full text like the MXO 4, but appreciate that might not be possible on the smaller screen Rigol.
