I watched only the ReMarkable device, as within Gallery 3 screens, if this video can help...
In there there are some comparisons on the color's rendition through different e-screens technologies:
Color E-Ink That Actually Looks Good: Reflection Frame with E-Ink Spectra 6
(the Spectra is not for ereaders, as yet it's very slow on refresh rates).

I don't know about the others devices with Gallery 3, I know the ReMarkable has had an upgrade to allow front light to be rised more.
Ps: I wasn't to know a laser, printed page has 1200 dpi.
Pps: pardon, but now I don't know if the videos can be seen enbeeded or if they requires to be watched on YouTube.
Edit: I wasn't to know there was a Gallery 3 1st version: as on the Bingme Galy, and a 2nd version, as into the ReMarkable Paper Pro.
