Yes I would say so: "the degree of leucism varies with a bird's genetic makeup. But the skin and eyes remain their normal pigment and color.". This is a partially leucistic bird with only some feathers being white - in some cases all of the feathers are white, however the eye and other bare parts generally retain their normal colour - albinism is when the bird is totally white and the eyes and bare parts lack pigment, being pink. (Partial albinism is not possible.) Interestingly, it is thought that very few albinos reach adulthood. In leucistic birds, the white feathers are not as strong as those containing pigment, which causes them to weaken and in cases weaken flight, making them more prone to predation.
Very interesting bird
@Niall Perrins is this leucism?

That's really interesting. Thank you for sharing
It's interesting that @Zach Simpson says that he has seen a lot of Drongo's like this if I recall correctly in the Harding area
Seen African Stonechat, Kurrichane Thrush and Fork-tailed Drongo recently with partial Leucusim
@Hugo Voigts saw this now on the Birdlife Port Natal WhatsApp Group https://www.bto.org/our-science/projects/gbw/gardens-wildlife/garden-birds/behaviour/plumage
