Er... yes, Apple's lawyers cherry picked a Samsung publicity image that was used by virtually every retailer selling Samsung phones.
If they did that, then fair point.
Meanwhile, here's the app drawer on a HTC hero (about a year post-iPhone) - which is what I had at the time:
Yep, I still have an HTC Eris sitting powered up on my desk as a clock. Loved Sense UI.
Note that although, functionally, it is a rectangular grid of app icons with a lower row of function buttons, the visual style is significantly different to the iPhone, whereas the Samsung directly imitated the style of the iPhone icons and function bar.
Yes, but not as exactly as people think. Even that internal comparison review document that was done after their phone came out, noted that their icons lacked some of the nicer iPhone qualities. (That doc also noted that the look was still too close and that they should differentiate themselves more... which they later did, and that's when Galaxy sales really took off.)

E.g. yeah, its got a phone handset icon on the call button, but it hasn't got a white handset on a shiny green button with rounded corners.
The green handset icon is a favorite topic of mine, because Apple could've used a different slant / color set than others, but they didn't.
Likewise, people like to bring up Samsung later using a microphone for their recording app, totally ignoring the fact that Apple wasn't first at that, either. HTC had done it years before in their WinMo phones:
In fact, the whole iPhone skeuomorphic touch friendly UI scheme was an idea similar to industrial touch GUIs that had been around for decades. Which is why a Dutch judge threw out Apple's slide-to-unlock patent. Partly because the NeoNode had done a slide unlock years before, and partly because it acted nearly the same as a spring-loaded industrial GUI on/off button.
Apple didn't come up with the idea of a finger friendly UI. Heck, even Star Trek TNG had done it in the 1980s.
"Xerox's venture capital arm had recently made an investment in Apple, and had agreed to show Apple what was going on in its lab."
... so no, it wasn't stealing.
Tell that to Xerox, who later sued Apple for pretending that they invented the GUI. It's an internet myth that Apple got a license in exchange for Xerox's investment. Not even Apple has ever claimed such a thing in court or out. It doesn't even make sense. No other early investor gave up anything in exchange for a pre-IPO purchase option.
