Do we get spectroscopy from these images? What are the chances we could get detailed information about the atmospheres of earth-like exoplanets at some point in the future?

https://en.wikipedia.org/wiki/TYC_8998-760-1 cites a paper with spectroscopy results.

> TYC 8998-760-1 b is a gas giant exoplanet which has a mass 14 times that of Jupiter, and a radius of 3 RJ. It orbits at a distance of 162 AU (2.42×1010 km; 1.51×1010 mi), or slightly more than 5 times the Neptune-Sun distance.[5][7] In July 2021, astronomers reported the detection, for the first time, of an isotope in the atmosphere of an exoplanet; more specifically, the isotope Carbon-13 (C13) was found in the atmosphere.[8][9]

Though it's not Earth-like, we have already got some data on exoplanets using spectroscopy.
