Are you referring to this?:
If so, it should probably be mentioned that the OpenGL ES (GLES) 2.0 support isn’t directly through the native GPU driver, but rather via the ANGLE graphics API mapping shim.
So it’s probably still worth benching perf with this against the native graphics driver’s GLES implementation, which in addition will likely offer support for more recent GLES versions (3.0-3.2).
It’s also worth noting that the ANGLE home page lists “OpenGL ES 3.0 -> Vulkan” support as “complete”. So you might get better than GLES 2.0 support through the GLES -> ANGLE -> Vulkan -> graphics driver path. A quote from their page:
With the Vulkan backend, ANGLE 2.1.0.d46e2fb1e341 was certified compliant to ES 2.0 in Nov 2019, and ANGLE 2.1.0.f18ff947360d to ES 3.0 in Feb 2020. ANGLE also provides an implementation of the EGL 1.4 specification.
