Could even be HV regulation issues..
The only tube color sets I know of that lacked DC restoration were GE sets.

It is more likely that HV regulation is your problem. If the picture shrinks horizontally and or vertically (ie. blooming occurs) during the changes in scene brightness that is a dead giveaway that HV regulation is not working correctly.
