Depends on the dinosaur, so goes my understanding it's mostly just theropods that they have evidence for feathers. T-Rex specifically however we have skin impressions of and it just looks like scales.

I watched the 2025 series of the same name and it's nowhere near as good. Big sections of paleontologists 're-enacting' their finds and discoveries that are pretty cringe.
