Maybe.
On my PC
$ octave
octave:1> __opengl_info__
version: 4.5.0 - Build 22.20.16.4815
vendor: Intel
renderer: Intel(R) UHD Graphics 620
extensions:
GL_3DFX_texture_compression_FXT1
.....
Similar to the X log
glWinSelectGLimplementation: Loaded 'cygnativeGLthunk.dll'
(II) AIGLX: Testing pixelFormatIndex 1
GL_VERSION: 4.5.0 - Build 22.20.16.4815
GL_VENDOR: Intel
GL_RENDERER: Intel(R) UHD Graphics 620
(II) GLX: enabled GLX_SGI_make_current_read
...
You can test the GL behaviour with
$ cygcheck -l mesa-demos | grep bin
/usr/bin/eglinfo
/usr/bin/es2_info
/usr/bin/glinfo
/usr/bin/glxgears
/usr/bin/glxinfo
/usr/bin/wglgears
/usr/bin/wglinfo
/usr/bin/xeglgears
..
