Nah, that would require spacetime to curve a lot more than it does. It’d also have to curve in the other direction (local spacetime is hyperbolic, “local” as in basically all of the observable universe). Calculations show the universe must be several times larger than the observable universe (I forgot the exact numbers, but iirc it’s in the single digits or low teens) in order to match even Hubble observations, let alone JWST observations.
IMO, it’s likely that the universe just isn’t as homogenous as assumed, or maybe that certain geometries that span across spacetime or movement of the galaxies simply make us think the galaxies are further away than they actually are, or both.
There is little to no reason to doubt the measurements within the galaxy, as that’s not far enough for any presence of dark matter to really skew things, nor does dark energy have a marked effect within areas of enough mass, like within galaxies. Though yeah there is some wiggle room on further measurements, hence the recent news furthering the idea that our galaxy sits in a less dense region. We’ve had evidence for probably multiple decades, but nothing is certain until it’s proved in several unquestionably accurate ways.

I was joking. Unless it was genius of course.
I seem to remember that the science isn’t totally settled on the distance to stars in our own galaxy so I am quite chill about cosmology.
