I'm not sure I know what you mean by 'samples'...
Konami provides 64 flags, in addition to the default flags and national team ones, but none of them resemble any real life flag that I know of. When you go into flag editing, nothing screams at you like, "there's the Real Madrid flag; I just need to change colors and delete some lines." That was the case for a bunch of the flags in PES2.
You can also create a flag from scratch, but the pattern options that I've seen don't look too useful, even though there's something like 8 pages of different patterns in the editing section. Maybe some creative editors can utilize this function to get the flags right.
Lastly, you can change the fonts for any text on the flag, which is new - although, again, not sure how useful this is.
On the other hand, the kit editing, which I have tinkered with, provides less editing options than past versions of PES/WE, but you can the vast majority of the clubs to look like the real deal. Unfortunately, the color options are significantly less than what was in PES2.
In all, there's like 4-5 kits I've had trouble with, either because the right color isn't available, or because none of the editing designs work very well.
