That very pale leaf of your Wax Plant (Hoya macrophylla 'Variegata')
is likely the result of being in a dark box during it's 5 days of transit time, which deterred proper photosynthesis. That leaf may not survive but as long as the remainder of the leaves look okay and the overall plant appears healthy, all should be okay. I wouldn't be too concerned about the tiny purple spots and dots; those may be a result of the plant being grown in a greenhouse or outdoors. My hoyas stay outside year round and often have small imperfections in the leaves. An expert Hoya grower told me years ago that leaf imperfections can be caused by insects nipping at the foliage, or the plants getting bumped by someone walking by, or by leaves blowing against other on windy days, etc. The red to purple leaf spots can be due to fluctuations in light and/or temperature.
I just went outside and took these Hoya leaf photos. The red color of the leaves on Hoya pottsii is due to the plant receiving a lot of sun; if grown in shade, the leaves would be green with no red coloration. The dark dots/spots are likely due to light and temperature fluctuations:
