Color shifting and texture compression issues when uploading stylized renders to web platforms?

Hey everyone, I have been experimenting with batch processing some stylized artwork through Deep Art Effects to use across a few design projects, but I keep running into a weird color shift and compression issue once the files are uploaded online. When I preview them locally in Photoshop or my default image viewer, the dynamic range and brush texture details look crisp and accurately graded.

However, whenever I publish them through this website or test them in standard web canvases, the midtones appear noticeably darker and some subtle edge stylization gets completely muddy. Has anyone else experienced profile mismatches between sRGB and Display P3 when importing rendered assets into web-based pipelines, or could it be related to how certain automated image compressors re-encode high-frequency neural filter details?

I would really appreciate any insight into what export color profiles or pre-compression workflows you all use to preserve stylistic fidelity without causing massive file bloat.
