See the What should be added as a single release? and What should be added as multiple releases? guidelines if you haven’t already (and Proposed (unofficial) digital media guidelines for the long discussion that shaped the guidelines).
In this case, the different cover art justifies a separate release, and the absence of barcode 5056467359286 may as well (although it seems pretty arbitrary whether barcodes are included on Bandcamp pages, and I think that they’re impossible to find without looking at the page source).
Catalog numbers on Bandcamp are also tough. Sometimes they’re included in the album text in the bottom left corner of the page. Other times you can get them from the cover image, but that’s often just ripped from a physical release. Some labels like Warp put characters like CD, LP, or D in catalog numbers for different formats, but other labels reuse the same numbers. These kinds of ambiguities are unfortunately very common when entering digital media releases.
