Xanthophyll exchange modifies the organization of the photosystem II antenna system and possibly the photosystem I antenna system.
Quoted textsource-backed
The xanthophyll exchange induces important modifications in the organization of the antenna system of Photosystem II and, possibly of Photosystem I.
Xanthophyll exchange modulates light-harvesting efficiency and increases protection from lipid peroxidation.
Quoted textsource-backed
Major changes consist into a modulation of the light harvesting efficiency and an increase of the protection from lipid peroxidation.
Xanthophyll exchange is specifically controlled by lumenal pH independently from the activation state of violaxanthin de-epoxidase.

Xanthophylls undergo dynamic changes in both composition and distribution among Lhc proteins in higher plant thylakoids.
Quoted textsource-backed
Recent work has shown that xanthophylls undergo dynamic changes, not only in their composition but also in their distribution among Lhc proteins.
