SUMMARY
I have a single monitor that I use with 2x scaling on X11. When using Wayland (with NVidia card) everything is unscaled and kscreen shows conflicting information


OBSERVED RESULT
Everything is unscaled.
The KScreen KCM shows 200% scale for the screen
kscreen-doctor shows:
Output: 1 Dell Inc. DELL P2415Q/D8VXF0150C7B enabled connected primary Unknown Modes: 0:3840x2160@30*! 1:3840x2160@30 10:1920x1080@50 11:1920x1080@30 12:1920x1080@25 13:1920x1080@24 14:1600x1200@60 15:1600x900@60 16:1280x1024@75 17:1280x1024@60 18:1152x864@75 19:1280x720@60 2:3840x2160@30 20:1280x720@50 21:1024x768@75 22:1024x768@60 23:800x600@75 24:800x600@60 25:720x576@50 26:720x480@60 27:640x480@75 28:640x480@60 29:640x480@60 3:3840x2160@25 4:3840x2160@24 5:2560x1440@60 6:2048x1280@60 7:1920x1080@60 8:1920x1080@60 9:1920x1080@60 Geometry: 0,0 3840x2160 Scale: 1 Rotation: 1 Overscan: 0 Vrr: incapable primary

Note the "Scale: 1"

EXPECTED RESULT
Everything is scaled by 2x, kscreen kcm and kscreen-doctor agree on scale value
