Is this a leucistic black-tailed godwit?

I was looking back over my old photos when I noticed this (taken at RSPB Minsmere on 24/09/2023). There is a group of black-tailed godwits, with a bar-tailed godwit amongst them, and towards the front of the group there is an entirely white bird. It is

associating with black-tailed godwits, and fits the shape and proportions of them, but it lacks any colour. I haven't seen this condition in these birds before. Do you think that is what is going on here?
