I had a Zenith in which the three guns reached equilibrium with slightly different delays, so the gray scale had three noticeable adjustments occur, one after another.
Maybe this could also be a channel change / source change blanking of some kind that happens to operate when first turned on? Would be interesting to see what it does when switching between sources or changing RF channels.

Hmm, changing sources causes a "fade in" for each input..
Also I have noticed a quirk, if the picture is bright, like a daytime scene in a movie, then goes to a night scene with a fast cut, the picture looks for a split second like the brightness is up too high, and then fades down to a proper looking picture.
I'll see if I can capture that.
