Just testing a simple single product Buy Now button in PayPal and finding that when clicking through to PayPal, PayPal will opt to show either one or other of two different flavours:There's this look:and then there's this look:Sure, I'm familiar with both, having experienced them both as an end user, and assumed it was down to the merchant's options or his choice of PayPal configuration.But testing - now as a merchant - I'm finding either one will show, as I say at random. Don't get me wrong, either flavour performs its job. It's just a bit unsettling. Do I need to be concerned? And why does PayPal do this?Update:From a bit more digging around, I believe these PayPal's terminology for these two themes are Classic and Enhanced. But I'm still no wiser as to when and where PayPal opts to show one or the other.
Testing a simple PayPal Buy Now button - but why are there two different PayPal looks?

It looks like they are doing A/B Testing. This blog article found that they were in 2010, so it looks very likely they are here too.
