question remaining is the aesthetic one regarding the look and feel of
over coated fine art papers.

The aesthetic part plays a role so you want a protection that is almost
invisible, doesn't discolour in time or delaminate. Epson's Ultrachrome is
very close to that for indoor work. The pigment is protected. The paper
coating itself however is not protected. From experience I know that
Hahnemuhle coating collects air pollution as if it has to clean the air. Two
weeks candle burning at Xmas will show a brown shift on unprotected
Hahnemuhle. It will not be better with other coatings. You either have to
frame behind glass or put a varnish or lamination on it. If Ilford gets that
nice solution of a thermo curing coating right it would be the easiest way
to make a protection. It also would be a nice way to make mat and gloss with
the same pigment  ink.
