Xwayland and color depth

A number of X11 applications/games that I use through GNOME (i.e., Krita, Hollow Knight, Minecraft) do not display 30-bit color correctly. As of 2 years ago, according to Reddit user & KDE contributor u/Zamundaa, XWayland on KDE Plasma does not support greater than 24-bit color. Is this also true on GNOME today?

Thanks.
