SDE sampler output mismatch

Model is this one: https://civitai.com/models/613147?modelVersionId=1293903 Image : https://civitai.com/images/52145465

Just look how beautiful the image is: in Forge I reproduced it completely (the image itself contains all parameters - just drag&drop it to PNG Info tab and then "send to txt2img", then generate).

Now let us reproduce the same in comfyui: here is the workflow: 0600.json

Comparison of Forge vs. ComfyUI:

I modified scheduler from normal to Karras, but this doesn't help either: the pictures are too different, and the quality is different too.

Updated workflow:

0600_1.json

The issue is with SDE samplers, which I haven't gotten to match at the moment.

Here's a workflow Workflow_0600.json that should be closer to the original, but not entirely. It's obtained by dragging the civitai image onto the canvas.

It uses nv as the RNG and the gpu variant of DPM++ 2M SDE. The original also uses Adetailer.

Thank you very much for this.

Image is closer, but problems with face, most likely because the Forge's workflow used ADetailer (which is specified in metadata of PNG file - this is what I didn't notice, but which is NOT automatically imported into ComfyUI)

Of course it would be nice if engineers from ComfyUI make parser of this metadata info and automatically attach ADetailer node at the end of workflow.
