Can’t help wondering - what makes that apparent?
The energy bars 
The photo is taken in february 2018. I cannot see when he was caught, he isn’t in the collection anymore.
Thanks, @bagguille .
What makes @Jormdeworm conclude that the image is ‘quite old’, though? Is it something about the Pokémon or something about the image? (Or is it that he recognizes the image and remembers when you took it?)
If you look at the charge bars of the attack, you can see that they have round edges. The image is changed in our days, now the edges are sharp angles.
Thanks for the reply. The charge-move segments do look different, just as @bagguille described. But the Exeggutor, itself, appears the same as mine do today.
@vorgriff3, maybe if you compare the ends of the leafs in the heads, in the oldone the ends are lesser yellow.
