Yes. What I notice is what I would call a slight veiling of the
overall tones with it being more evident in the lower values, a sort
of haze that is more visible at an oblique. It seems to take 4 or 5
days to completely disappear visualy. I haven't bothered to measure it
beyond a couple of days but do consider it when making test scales and
profiles etc.
Your week is probably sufficient but significant change would be easy
to test for.
