with the honda, nothing much stands out apart from the blue drain plug and the gold sprocket.
on the yamaha, the orange brake stay, the gold barrel & gold tank cap, blue cap on rocker box and really polished motor i dont see anything else really wrong with it.
There is a fine line between overdone and underdone. I just see it that these guys have taken a little extra care and time with things and havent be constrained buy budgets and didnt just think 'oh that will do' and leave a few dull average parts etc on there, plus they wanted something that will stand out a bit.
