The original caption of your first pic reads:
"A portion of the dwarf galaxy Wolf--Lundmark--Melotte is shown, as captured by (from left) the Spitzer Space Telescope and the James Webb Space Telescope."
I think both Spitzer and Webb are actually showing a small portion of the blob from your last pic? Tried zooming on that last one but there's no way I'm going to find that specific section.
I could not match the ESO pic with the IR's either.
You are probably right .. the IR's are closeups of the "blob" -- minus the pink dust.
