The field isn’t flat so not the best photo. I’ve since found out his sire was croup high but didn’t affect his jumping ability to 1.40cmIf that is a genuine, level, photo I have to say I doubt he will catch-up fully and I would think he will always be slightly downhill.
However, lots of horses are built downhill so I wouldn't unduly worry but would bear it in mind in his work when you get to that stage.

Many do this and level out, some stay a little Hugh behind but you get what you get nothing you can do to change it.
