I guess though, I need to do a lot of studying myself on the species to make it truly "my own" tick and not a tick because someone else told me what it is.
Also, I would expect to see some white on the tail feathers protruding from the undertail coverts in pic 2.
...if the bird were a Northern. Sorry my wording wasn’t so clear.
And yes, in my view this is perfectly tickable as an Isabelline but like Chris said «your list, your call».

I too would veer towards Issy on structure, being a juv means it is not as IDable is an adult might be and it has also been photographed in strong sunlight which brings its own problems...
