Did you have a specific concern?? Shape?? Size?? Color?? Weathering maybe?? Mine come completely clean(un-weathered) to ensure that the weathering over the decal will match the armor perfectly. If I weathered them ahead of time, there's a good chance that it will NOT match the armor weathering(colors), and stand out THAT way....
Lot's of options here, just depends on what you're looking for.....
I believe I figured out what the actual issue was. He purchased a "shoulder decal"(an ESB version), not knowing he needed the ROTJ version. That's where his question of "accuracy" was coming from. Either way, if you go with Daz's stuff, you can't go wrong.....
