Yes. That's how Kaleido works. Kaleido is an RGB filter placed on top of the screen, which means the colour PPI is lower than the BW PPI, due to multiple white pixels being required to simulate a single pixel in another colour, e.g. 2 white pixels --> 1 red, 1 green pixel in the colour filter = 1 yellow pixel.

Since the colour filter is always on top of the BW screen, you can never "turn it off". As a result, even BW content will look worse than on a purely BW panel, even though the panel is technically 300 PPI. The screen will also be darker, since much of the light is being blocked by the filter at all times. Some people are willing to make these tradeoffs in order to get colour, and other people are not.
