Follow-up to #61847, which fixed this for class casts. The same thing happens when the JSON column goes through an Attribute accessor that returns an object.

protected function settings(): Attribute
{
    return Attribute::make(
        get: fn ($value) => new Fluent(json_decode($value, true)),
        set: fn ($value) => json_encode($value),
    );
}

$user->settings->theme; // "light"

$user->update(['settings->theme' => 'dark']);

$user->settings->theme; // still "light", no UPDATE is sent
