Higher Quality Depth Buffer image?

Hey guys,

I am wondering if an option to force a higher quality depth buffer image would be possible? I use Reshade to composite screenshots together using the various debug controls. For instance, I take a screenshot of the depth buffer and use it to composite high-quality depth of field in Adobe After Effects. The problem I am having is that the depth buffer image doesn't look like the output is 32bit. The image has hard edges where the black/grey/white is transitioning. This makes it hard to use when compositing because it makes the depth of field in After Effects have some unnatural transitions with weird hard edges.

Is it possible to get a debug option to force a higher quality depth buffer? If needed I can supply images showing exactly the issue I am having.

The depth buffer is usually saved in a 24bit integer format. The remaining 8bit are used as a stencil buffer.
This cannot be changed in most cases, because there is only one 32bit float + stencil format, which there is no widespread support for.
