By looking at some artistic painting and comparing it to the apples you see in TV adverts you can see that there is a difference between them.
The apples in paintings seem to be more realistic and revealing to all the different types of apples, including those with bruises and with different colours etc. Artists tend to show the truth in heir art and don’t try to hide the scars and secrets that’s why the apples in painting seem to be less “perfect” or less commercially viable.

Whilst the apples in TV adverts or movies for the most part are ripe bright red apples that are the most appealing to customers, whilst they barely show ones that are completely green, or different shades of orange because for the most part they are less appealing then the bright red ones.
