Were the Tiger-class cruisers the final victims of the naval treaties?

No. Continuing government constraints forced the Royal Navy to balance adequate cruiser capability against the size and numbers it could obtain.

The Royal Navy was trying to obtain enough ships while preserving the capabilities it expected from a cruiser. Its preferred larger vessel would have carried at least three twin 6-inch turrets and four 3-inch mounts. Larger command facilities could also have prolonged its useful service. Government funding constraints pushed the design toward a smaller compromise.
