I'd think the difference would be nearly unnoticeable.
It's like this.....,
Those who have done up a "Light Fusion" and done it 'rightly' can swear by what they see.
A properly done Light Fusion...in White or Gray shade, has not "many layers" but really only the equivalent of 3-4 very light coats. Those who have attempted to discount the concept have almost everyone to a man "Rolled ON" the paint. A single "Rolled" coat is equivalent to 4-5 sprayed coats.
Ever since we have increased the translucency of the paint, and upped the reflectivity quotient, "White Light Fusion" has become less a necessity as it has become a rarity. At the start,(2001) when white screens were the accepted Status Quo, Light Fusion offered real improvements in depth and dynamics. But it didn't do much for improving received Contrast beyond what the PJ / Screen combo could offer. And whaddya know...if that was the one thing lacking...it was going to become the one thing focused on.
So the Top Coat (MississippiMud) got a slight infusion of Silver Metallic. And one must consider that before Light Fusion there was SM/MM (Silver Metallic-MississippiMud) where the Wall or Board was completely coated with pure Silver Metallic Paint, the "Roll Coated" with just enough White MMud to produce a even, ultra light gray surface.
No one ever questioned the ability for light to pass through and react to the underlying SM. In fact several Screen Mfg used a similar approach, as do some do to this very day.
All those instances involved substantially thicker material or coatings than what was ever advised to use with Light Fusion.
When Black Flame / Silver Fire came along, the improvements they ushered in made "White Light Fusion" much less necessary...as the darker Gray surfaces still retained both Gain and deeper Blacks. Add to that the general unavailability of decent sized (60" x 96" +) 1/8" Acrylic Mirrors at affordable prices past 2006-7 and really...it's just a simple matter of not enough opportunity.
However....when I'm attempting to use Silver Fire in a 6.0 +
configuration, and I can get a Big Mirror...or Tile several together, the added light reflectivity available from a Mirror being underneath the dark Gray paint does make considerable difference in the most important way.....maintaining white levels. And it does so much more effectively than a White substrate.
Kinda a moot point though....unless someone is restricting themselves to a 98" diagonal screen (85" x 48") that needs "considerable
ambient light assistance". If so, than a ultra dark gray SF coating on a smaller sized Mirror can...and will be a superior choice over any mere white substrate.
