To the best of my understanding, the filters used by ClearInk are the same used for LCD manufacturing - hence, they go from 96dpi to "a lot". The filters per-se are not an obstacle.
But the observation is right: there must be subpixels - each logical composed by more physical, smaller than the logical. On the other hand, all colour displays I can think of have subpixels, with the exception of common e-ink and, I understand, AcEP. Surely, it would have more resolution as monochrome, but neighbouring technologies do not seem to have particular problems achieving high resolutions... Although, as DuckieTigger noticed, there are "optical micro lenses" involved.
On this regard, I am not sure how to get the white out of it: you get white on light-emitting displays by fusing red green and blue, and in TIR you have no light emission but an effort to have maximum reflection... Is that reflected light enough to get a good white? The less convincing effect of the videos to me was in the white rendering.
Also, I remember some statement like "we get double luminosity of epaper, but after the color filtering we get even" (very broadly, I have not re-checked the source).
