Default TV (direct) channel color variation

I recently purchased a 27" Sony KV-27FS120 and most of the time, the picture
is great. Sometimes there is quite a bit of color intensity variation from
one channel to the next.

1. Is this something a TV should automatically correct for? if so, what is
that function called?

2. Is there an adjustment or setting that can engage or enhance this
corrective funtion?

I am not a tech but I am also not adverse to making internal adjustments
that don't require the exactness of a scope.

Thanks.

Auto Chroma Control ACC. It looks at the amplitude of color burst and
adjusts it to nominal. If the burst / chroma is getting messed up
somewhere, the ACC will 'fix' it but it won't be correct. Are you
comparing off air TV stations or a cable feed? I'd expect less
variation between TV stations than cable.

Dish Network. Seems worse on the regular VHF channels that the others. Is
there anything that I can do to improve the situation??
