This is reporting on Yan et al, which is a paper using data of one of the first-release JWST publicity images planned by the telescope institute, and has already been called out as with issues. It is of SMACS 0723-27, one of the most significant gravitational lenses yet discovered, so yes, the warping of space-time is problematic, as galaxies are indeed amplified, stretched, multiplied by this distortion, and given in some cases a significantly deeper view than direct observation.

This should be first a study in further mapping the gravitational gradient, the nature of dark matter, and not jump right to finding redshifts from imaging. JWST's NIRCam imaging is actually a bit wrong for Lyman break astronomy at the (unexcitingly not-so-deep) redshifts being found, as the coarse transition from 200W to 277W is across two different instruments of different resolution and still faltering calibration and backgrounding even across adjacent sensors, along with cosmic ray flux and algorithmic removal that makes almost nothing pristine light.

Also it is clear that the nature of what is found early, but closer and actually resolvable, is going to create biases. Various radiance of active galactic nuclei, early formation of globular clusters, mergers, etc skew the spectra, and we still don't have spectral observations deep enough to show emission lines (Arizona paper).
