Thank you as well - usually marketing can be counted upon to do, "Everything under the sun to drive Sales..."
This MCU's founding firm - LMI - introduced both a mono graphic (similar to the one you've just chosen) & bit later a 3.5" TFT - both revealed rather clever screen designs. (i.e. nice combination {I thought} of images, graphs and numeric data) The 3.5" design was distinctive (again, says me) you may have to dig a bit to find it - but believe you'll benefit from that effort. The mono design was for a 3 headed, Stepper Motor RDK - and employed not one, but two, MCUs. Iirc - that was released prior to the official graphic library.
By the nature of your initial question - believe that your pursuit of, "Purposeful Screen Layout/Design" - which does not strictly rely upon the "crutch/splash of color" (to compensate for rushed screen development) - will indeed serve you well.
Note too that 2.4", QVGA, TFTs may today be purchased for less than most QVGA, mono Lcds. (J.K.: "Now he tells me!") And the TFT likely has superior contrast & viewing angle - 2 key, "figures of merit" for displays. Demand and review the display specs - auction sites & other mass markets may not offer best quality to the "unaware." (and that's not you!) Bon chance, mon ami...
Have to sell something now - but if you desire - I'll later post several screen designs which - along w/6, 12 hour days/week - for 3 years - helped take my past display firm from start-up to public...
