Form follows function - pov (point of view) puts some twists on things, plus people - at least some people - experiment and or do not follow convention, sometime with perfectly adequate and useful results, sometimes not.
Matte paper mounted and spray coated and displayed out of the way of abrasion (a wall for instance) - seems like I see this happening here and there, I do so with my own stuff - and things are rosy and swell. The papers are also "closer" to the viewing experience. Not all Matte papers can do this, but many can.
Gloss behind glass sucks to me. Gloss under clear gloss lam is strong and is - well practical for many applications (form follows function) and from that perspective looks really beautiful to me. And displays proudly and without much fear of damage or degradation.
Durable, abrasion resistant, smoke resistant, adds depth, ... cheap is sometimes a learned perspective that may simply be an assigned adjective for cultural not practical reasons, then continued by momentum and traditionalists. Oh, and the print looks great hanging on a wall, better to my eyes than canvass because more detail and what I call richness. Please tho, each to their own ...
Just my thoughts ...
Cheers

PS I know the customer is always right saying, but for some folks the creating is the goal, and like some "baseball parks" we "build them and they will come". Historically there are artists that went this way and did fine, and their still are.
