Peak memory usage is at 3632MB which is 400MB below your GPUs total of
4032MB, as to be expected due to your setting of
opencl_memory_headroom=400.

which is really close to 400MB. Note that darktable (as any program
using opencl) has no means to detect the free amount of GPU memory at
any time, so it relies on having access to all minus opencl_memory_headroom.
I suggest to set a significantly higher value for opencl_memory_headroom
like 800 or even higher in your case. You have a lot of memory, no
problem to be a bit more permissive.
