Dependence of the inner-radius emission contribution on the wormhole parameter λ. The solid green line represents the observed weighted flux ${\int }_0^{2\pi }{\mathit{g}}^3ϵ(r_{\mathit{in}})d\varphi$, while the dashed blue line indicates the evolution of the inner disk radius, r_in. The vertical dotted line marks the critical value λ_c ≈ 0.14, where the wormhole throat exceeds the ISCO radius. For λ > λ_c, the observed intensity exhibits a non-monotonic behavior due to the interplay between relativistic Doppler boosting and the radial dilution of the emissivity, ϵ(r). The model parameters are a_* = 0.998, θ = 75°, and q = 4.0.
