`Pkg.precompile` within test sandbox prints without color

I've tried to understand this but the io types passed around in Pkg and how color is determined on them in Base is pretty complicated. @KristofferC does the reason jump out to you? Note that apart from the main Pkg.test precompile, the only ones that show up without color in Pkg tests are the apps tests, which don't specify the io specifically.

Just to add a datapoint, this is running Pkg.instantiate in v1.10 (top) vs v1.11 (bottom) in GitHub Actions:
