Nope, your trace will work in both cases. I tried the trace from your system:

It begins with warnings regarding __, and then:

0 14363 glLinkProgram(program = 616)
14363: warning: error: linking with uncompiled shader
14365: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glGetUniformLocation(program not linked)
0 14365 glGetUniformLocation(program = 616, name = "m_W") = -1
14365: warning: glGetError(glGetUniformLocation) = GL_INVALID_OPERATION
14366: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glGetUniformLocation(program not linked)
0 14366 glGetUniformLocation(program = 616, name = "m_iW") = -1
14366: warning: glGetError(glGetUniformLocation) = GL_INVALID_OPERATION
14367: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glGetUniformLocation(program not linked)
.. and a lot more of that. 

Then during rendering:
16650435: glDebugOutputCallback: Medium severity API performance issue 9,
Stalling on the GPU for mapping a busy buffer object

16652177: glDebugOutputCallback: Medium severity API performance issue 12,
Flushing before mapping a referenced bo.

16652177: glDebugOutputCallback: Medium severity API performance issue 11,
Mapping a busy BO, causing a stall on the GPU.

16656049: glDebugOutputCallback: High severity API error 1,
GL_INVALID_OPERATION in glUseProgram(program 1716 not linked)
0 16656049 glUseProgram(program = 1716)
16656049: warning: glGetError(glUseProgram) = GL_INVALID_OPERATION

The light passes show up correctly on screen. But the gamma value is far too
high.

So that means Metro LL uses different shaders or assembles shaders in a
different way depending on the GL version/vendor/extension info provided by the
driver?
