Of course there is. But few people understand the physics and mathematics that prove that any passive eink-like device using RGB is inherently very dim compared to printed photos or printed paper which uses C Y M (for paper C Y M K and quality printing even more shades). There is a good physical reason why inkjet and laser printers use C Y M K (or two densities of C Y M on some inkjet). R G B printing is technically possible. It has been since the Victorian era, but it's either very dark or unsaturated pastels.

Also RGB reduces the resolution to either 1/2 on both directions (Bayer) or 1/3rd in one direction. C Y M uses transparent layers which is why currently it's limited to printing, no-one has invented a panel layer that's either clear or Yellow (i.e. only blocks blue). CYM works by each layer blocking less than one third of the spectrum. RGB works by each dot blocking more than 2/3rds of the spectrum and has loss on the desired Red, Blue or Green.
It might be a little better than Triton and Kaledo, but not enough for the mass market. Only some comics/graphic novels really need colour. Regular novels and most textbooks don't. Cookbooks and typical "coffee table" coloured books will look rubbish on this and most coloured illustration actual books need a 10" display.
