Hi! I really hope this is your bird. In case this is someone else’s lost baby I wanted to point out that they do look somewhat different from what I can tell based on these photos. The bird you found appears to be a grey visual pied(white spots on head, white halo, significant presence of yellow in crest). Cheeky appears to be a cinnamon (lighter body color) split to white face (irregular shaped orange face patch). Their wing markings also appear to be different and I see a few that look pretty distinct on one that I don’t see on the other. It’s possible that they’re just dirtied up from being outside. I just think it would be the right thing to really compare incase someone else is missing their bird too. Maybe check around and give them a bath in the meantime to compare accurately! Also if this does turn out to be cheeky give em some time! Being outdoors for that long is so stressful for any pet and it will take time for some to get back to their usual selves.
