The Special Theory of Relativity introduces the relativistic frames of reference by introducing an additional frame of reference, mathematically, for presenting relativistic events within the universal frame of reference.
A co-ordinate geometrical digram of relativistic frames of reference can be presented within the universal frame of reference under the influence of gravity.
As for example, when we present the digit 1, it's magnitude is considered as the difference between 1 and 0 so that (1-0) = 1, necessarily we do not mention 0 or the difference between them to present the magnitude of 1.
Similarly, when introducing an additional frame of reference, that would physically mean a mathematical or geometrical introduction of another frame of reference, within the universal frame of reference even when not defined.
Therefore, relativistic events are relative universal events, and they occur within universal frame of reference, and therefore follow universal applicability.
The Lorentz transformation is no exception in terms of universal applicability.
