For human subjects, you might want to shy away from canvases with lots of OBA's, since they tend to go a little lurid under certain lighting conditions such as fluorescent light. Which is not a bad thing for most other subjects. For instance it has been long established that luridism in landscapes is a potent sales tool. And even canvases without OBA's can show a lot of color variation under different kinds of lighting, hello Metamerism. You have to test with actual images and canvases. Sometimes you can run into a problem with smallish portraits on canvas where excessive texture gives the subject a warty appearance. Best to stick with larger prints. I think Ilford has a couple smooth canvases specially intended for portraits, anybody have feedback on that?
Last night I made prints on 44, 36, and 24 inch rolls of the same brand of high $ canvas. Each roll has different amounts of texture, apparently different weaves, and slight variations in color and contrast for the same image. Canvas users need to cultivate fatalism. If it weren't for pumpkin pie and coffee, I would rant.
PS, while Sunset Select is indeed a nice, smooth canvas, Lyve really does have significantly better gamut that shows up most notably in green foliage and blue sky gradations. But every few months I buy a roll of Lyve for testing, and there has always been an issue with the substrate such as varicose veins, excessive stiffness and/or texture, and most recently islands of excessive, head-swiping thickness. Other than that, it's pretty sweet as matte canvases go. I suspect it all comes down to the contract manufacturers that make the stuff, and I suspect there is quite a bit of hair pulling at BC because of this. If Lyve were on a reasonably supple, minimally textured 18 mil substrate it would be Heaven on Earth. Not that Sunset is foible free either, but its flaws seem easier to work around.
