No, but do you have evidence to state otherwise? The fact is that plasma uses phosphors that age rapidly within the first 500 hours. With break-in slides, which typically consist of red, green, blue and variations of white/black, you are guaranteeing that those phosphors are aged evenly over the first 100-200 hours.
If you watch regular content, the phosphors will age but, most likely, at a variable rate. It will eventually catch up to other phosphors and even out, but the time it takes to do so may be longer.
I would suggest a break-in if you want to get your set calibrated, either by an ISF professional or a DIY job using a colorimeter. Your picture does change within the first few hundred hours. Break-in assures that the service menu calibration that's done will last you a while.
