I have been a painting contractor for over 30 yrs In new england.
in he past 15 or 20 yrs we have speced high gloss on ex trim with semi or
soft gloss for the body.This is for high end residential projects
It does clean easier and looks new longer.

have always used oil based semi and gloss for interior trim

Nothing is changing, the right paint and sheen must be picked for each
job. Sherwin Williams has 5 levels of sheen if I remember correctly. In
houses flat may be better for one room , high gloss another. It is what
is apropriate for the job that is important.

Magnusfarce is asking about exterior paint.
Satin or other gloss paints are easier to clean and may be desirable for
interior trim, but can look strange on wall areas, unless in small rooms
like bathrooms. Re exterior, why would you want any gloss at all on the
outside? I've tried semigloss on exterior trim, but it doesn't look so
hot,
and tho cleans easily, does not outlast the flat used on trim. I think
flat
acrylic also breathes better, so may be more resistant to bucking/peeling
due to trapped moisture behind the paint. I know of no such industry
"changes" in finish preference for outside paints that your dealer refers
to.
