No, Gallery AKA ACeP is not even anywhere near good enough for an ereader. 10 times or more slower than regular eink, which is poor for a general purpose tablet (I have one and only reading ebooks & PDFs is any good).

No, R&D doesn't really work like that.
Colour bistable screens obviously needs a new technology. Kaleido is just a CFA (translucent printed pattern) on mono eink, which is only marginally better now than 11 years ago.
While Gallery / ACeP is a better approach being Subtractive colour link print, thus could be 3 to 5 brighter than CFA on mono, it was first announced May 2016, that's over 8 years ago, and it seems unlikely to ever be fast enough for an ereader. It's aimed at retail signage, and losing there. It seems doomed to follow Mirasol and Plasma TVs into the bin.
Kaleido is nothing new at all. Baffling why they ever bothered with Triton (except it used an original type odf LCD CFA). Kaleido is limited by three things:
1) It's just dots on a mono panel, so always 1/2 resolution.
2) It's R G B dots that only partially covering each pixel, so pastel. This is what allows a pseudo mono mode.
3) R G B dots in theory can't have a brightness better than 1/6th of mono, if perfect and covering the pixel. Physics that can't be beaten. That's why they only partially cover a pixel, to increase brightness.
They can tweak Kaleido dot density and size, but it's still only good for comics and much worse without front light than mono eink. All the advantage of eink over the best matt screen OLED, QLED and LCD panels is lost when you have to have a front light. So Kaleido is doomed. A short term attempt by companies that only do eink to have colour.
