  We use angle-resolved photoemission with circularly polarized excitation to
demonstrate that in the 5x1 superstructure-free Pb-Bi2212 material there are no
signatures of time-reversal symmetry breaking in the sense of the criteria
developed earlier (Kaminski et al. Nature {\bf 416}, 610 (2002)). In addition
to the existing technique, we suggest and apply an independent experimental
approach to prove the absence of the effect in the studied compounds. The
dichroic signal retains reflection antisymmetry as a function of temperature
and doping and in all mirror planes, precisely defined by the experimental
dispersion at low energies. The obtained results demonstrate that the
signatures of time-reversal symmetry violation in pristine Bi2212, as
determined by ARPES, are not a universal feature of all cuprate
superconductors.
