Having not walked on these, have worked with a number of other violet CTP.
And what your report are classic signs of other CTP of a dirty spinner mirror, when these get dirty they do 2 things, lower the power to the plate so highlight dots are lost, but also defuse the dot, so not a tight focus dot, so highlights are lost but shadow ends spread.
other cause can be bad focus, but a lot of violet machines did not have focus adjustment systems as not needed on violet so would be factory set, only needing adjustment if laser changed.
