Having that info and the data you’ve just mentioned they postulate if it’s habitable or not. Obviously not seeing any detail at all about land mass shapes, but perhaps composition? I’m not a spaceologist, so I’m only musing.

Yeah, but it’s still just a single pixel of light from the star. It just changes color slightly when the planet passes in front of it and the atmosphere gases absorb certain characteristic wavelengths.
