Na, standards are given by the norms DVD and Blu-ray are giving, so you cannot change that (NTSC / Pal / Secam norm, in fomer times VHS or LD norms). Variable only are releases by web. I do not see where standards have been changed. Cenosrship / pixalization are varibale over the years and the studios active atm have not changed since some years, the only thing what has been adapted lately is the running time of episodes.
