Regency: what color should it be? Seems like Realm changes it a LOT

UPDATE: CONFIRMED. The realm VASTLY changes the appearance of the Regency tileset, even with NO minor card played. The screenshots below with dark grey walls and white foundations and pillars are in an Ascended Astrolabe Foreset realm.
But when I built the set in the Crossroads (again no minor) the foundations and walls are all the SAME color and MUCH lighter grey, nearly white, as everyone has said.

TL;DR so i built this huge base in a realm i like and it turns out the lighting filter it applies is somehow breaking the Regency tileset T_T

I cannot imagine this to be intentional (look at the VAST difference between the walls and the pillars) so please fix it so the walls change less dramatically

(Weird that the walls color changes butt he pillars don';t....)

See screenshot. This is my Regency build in an Astrolabe Forest (ascended) with no minor cards in play. Note the foundations and pillars are white, but the bulk of the stone / walls are grey.

Several folks are telling me the walls in the preview video show the entire set's stone parts as white. I've asked in the Discord but only gotten one answer who did not respond to followups, but they did say theirs were also white.

I have an RTX 3080 and do not mess about with intricate custom settings; defaults and High or Ultra in-game.

How is this possible, that some things are white and some are not? IS this supposed to be a white stone house, not grey? I have no idea what to even change or test here.

UPDATE:
Clean reinstall of drivers, every video preset setting, evey Lumen level setting, every DLSS setting. Nothing. No difference. Grey Regency as shown in pic.
Adding a new screenshot with F2 info in case it helps.
People are swearing to me that this should be white stone.
I don't get it.
