Chromium falls back to a software GL implementation in headless mode (Mesa, then SwiftShader): https://bugs.chromium.org/p/chromium/issues/detail?id=617551

As of 2019 you can manually force hardware GPU usage via EGL on some platforms (Linux, macOS): https://bugs.chromium.org/p/chromium/issues/detail?id=765284
