Most likely the silkscreen is correct, so you'd just have to follow the silkscreen, test a bit. There are a few types of purple R2040 boards too. For example, it may be a cheaper version of a better purple 16MB-type board -- if there is good demand for something (the 16MB being the primary selling point for this one), someone might try to manufacture a (cheaper) batch and feed it into the Shenzhen market.
Once I deliberately went looking for a clone-like Pico board and found one at first try:

(I always buy Pico boards from resellers, except when I am trying to fish for dodgy stuff![:D]( "Very Happy")
)
It would be useful to identify the LDO regulator and the VBUS diode. If you can read the markings on them, those here can help to identify the parts. If the LDO is of the really cheap kind, don't run large loads on it or you might kill the LDO. I think the diode should be okay since it's a SOD-123, it's a Schottky if it doesn't drop more than 0.4V or so.
