I've heard of something called "Bloom" Does that sound similar to what I'm describing?

What you describe is hard to understand...
If you had a blank raster or unchanging test pattern the set should not flicker of change brightness. What blooming typically manifests as is an overload of the HV supply. Less HV makes for dimmer picture and bigger deflection since less HV means slower electrons that hang out longer in the yokes deflection field. Blooming is typically either constant (beam current set far too high) or dependant on average brightness of the video image displayed.
I've never seen a set display something that looks like a tape artifact unless connected to a tape deck....there is a phenomenon known as retrace lines that occurs when screens and or brightness is too high....
You need to post some pictures.
