  A theorem of Gutt-Hutchings-Ramos asserts that all normalized symplectic
capacities give the same value for monotone four-dimensional toric domains. We
generalize this theorem to arbitrary dimension. The new ingredient in our proof
is the construction of symplectic embeddings of "$L$-shaped" domains in any
dimension into corresponding infinite cylinders; this resolves a conjecture of
Gutt-Pereira-Ramos in the affirmative.
