The best way to get this information is to call:
glGetString(GL_VERSION);
Which will report something like this (Fido-Krogoth 3.14):
OpenGL ES 3.0 V5.0.11.p4.25762
Also, the kernel boot messages report this during boot:
Galcore version 5.0.11.25762
OpenGL ES 1.1 and OpenCL are different libraries. The release notes detail the API spec versions targeted.
