I want to get my house pressure washed and I am reading that I should

Anyone care to chime in?

Depends on how the bricks were fired.
Hard to tell, except you should try a small place that doesn't show
first, then decide.
I've heard that steam cleaning some bricks causes them to suck up
water and dirt afterwards. Pressure washing might do the same.
That's all I know. Always had brown or dark yellow bricks that never
needed cleaning.
I've seen some painted bricks. Bad idea.
