It's not 300dpi just because you can do black at 300 dpi with coloured edges. Do read how subpixel addressing works and how anti-aliasing works. Despite your confusion a 300dpi panel with colour filter on it for 150 dpi colour can never equal a mono panel with no filter even with mono content.
You are simply describing sub-pixel addressing.
You are misleading people. I've explained carefully why with mono content it can look better than 150 dpi, but can never equal a 300 dpi panel with no filter on it.
Also for decent eyesight or proper reading glasses the consensus is that you need 200 dpi colour minimum. Then you don't need sub-pixel addressing and can use regular anti-aliasing. I've texted many LCD panel resolutions and it's the same principle, a mono panel with a colour filter. A 150 dpi colour isn't good enough. If you want to read novels you'd want a 200 dpi colour panel, i.e, if 2 x 2 cell, a 400 dpi mono under the filter.
This is out of date as it only has stripe filters, not 2 x 2, but the explanations and conclusions are still true.

Differences and similarities of eink colour (Triton or Kaleido, not Gallery) and LCD:
Both use a mono panel with a colour filter. The exact same design of filter could be used, but Kaleido uses less pure colours to improve brightness.
There can be stripe, 2 x 2 and pentile layouts.
The eink only has 14 grey levels, black and white. The LCD has 254 (standard) to over 1000 levels (HDR).
Black on both is opaque. White on LCD is clear pixels. Reflective (eink) vs Transmissive (lcd).
There is no difference to black resolution on eink colour (Triton or Kaleido, not Gallery) and any other colour panel using sub-pixels of primary colour. No-one claims an HD colour LCD is 4K for black, but it does black at same resolution as an HD Kaleido display.
Sub-pixel addressing on a 2 x 2 colour matrix 150 dpi can create an appearance of 300 dpi, but it's nothing like as good as a native 300 dpi mono and how good it an illusion it is depends on the viewer. The "improved" quality is controversial, which is why at 200 dpi and higher colour it's normally not used.
No-one claims a colour LCD has it's native resolution with monochrome text, because it would be a lie. The same applies to Kaleido or Triton eink.
