Is this an official DexThemes product?

DexThemes is free, open source, and community-built. It is not affiliated with OpenAI. This palette comes from the built-in Codex theme catalog; DexThemes provides the preview and import handoff.

Does DexThemes modify Codex files?

No. DexThemes prepares an import string. Codex owns the final Appearance import and asks you to approve the change.
