We revisit Dp-brane holography, constructing Coulomb-branch solutions that describe a spherical shell of Dp-branes. The resulting throat geometries contain a flat-space bubble in the infrared region, providing a concrete framework for exploring entanglement in flat-space holography. We argue that the presence of the flat-space bubble leads to an overall reduction in entanglement and a corresponding decrease in the effective number of degrees of freedom in the dual boundary state relative to the standard vacuum. We also investigate holographic complexity in these backgrounds.
