Frankly I'm not convinced.....the issue is who borrowed what from whom.
Accusations of ripping should be left via email to admins, as 'wrong' accusations are 'libel' and therefore defamatory or even actionable.
There so far is no evidence that the second work has borrowed anything at all from what was exclusive, original content in the first work.
If you wish this to be public then the accusor is required to provide evidence that work unique to his own creation, not available from a third source was plagiarised.
At this stage there is no evidence of any kind that BOTH works may not have 'borrowed' their origins from a third.
This is not about a pixel comparison, but whether one or either was the first to apply exactly that style of glassy gradient.
Currently, with over 2600 WB skins there is an extremely likely chance of close similarity occurring, but until it can be demonstrated that it is not a case of both being derived from the same source then no definitive decision can be reached...
